DK Summit

DK Summit (known as DK's Snowboard Cross in PAL versions) is the third course of the Flower Cup in Mario Kart Wii.

Flap	30.654		31.770

DK Summit has multiple zipper bypass shortcuts (zipper cuts), and currently benefits from the use of supergrinding in both 3lap and flap categories, as well as superhopping and supersliding in flap categories. Hence, it has two 3lap and two flap categories. The Unrestricted 3lap and Unrestricted Flap records are technically the No Ultra 3lap and No Ultra Flap records respectively since no ultra shortcuts are used in either TAS.

The current strategy for UR 3lap is to perform the fastest zipper cut every lap.

The cannon is entered on the right side and the fence is hit upon entering to perform a low cannon, assisting with deceleration upon exiting it. When landing after the cannon, a hop is used to decelerate quicker than braking (this works due to the slope), followed by a SSMT to face the opposite zipper. The first mushroom is used to accelerate, perform RFH, and then a zipper bypass with a wheelie trick. The zipper boost allows you to go through the offroad without speed loss, where you perform a rehop and a rewheelie to align for the moguls section and prevent a wheelie chain.

Once reached, you trick off the gap between the second and third moguls from the left, before landing the trick on the mogul immediately behind them, holding a drift, tricking a second time, landing on the mogul immediately behind that, then delaying the the third trick long enough to perform a wheelie trigger off the next mogul. In total, 3 wheelie triggers are sufficient to reach the right side of the boost ramp at the end, where a rehop is performed off the right edge of the mound in order to stick to the very sloped side edge and get perform a broken wheelie rotation.

When landing from the broken wheelie, a rewheelie is performed to attain both a partial stick to the edge of the track and a significant rotation due to the high pitch when the brief drift occurs. This wheelie leads immediately into a first-frame hop off the edge of the slope on the opposite side of the first chasm, which converts EV from gravity to sideways momentum, helped further by a neutral glide. This sequence ends with a momentum hop to preserve EV to the boost panels. On the zippers, rehops allow for frequent restarting of zipper boosts and wheelies. On the final turn, a slip drift to the left is done to stick to the zipper surface and turn to the right. On laps 2 and 3, the reject road on the fence are used to let you gain large amounts of XZ speed.

The current strategy for the UR flap is to perform 3 zipper cuts, each using 1 of the 3 mushrooms available.

To enter the lap, a double trick off the zipper on the left side of the last turn is used to maximize the trick boost carried in. No strategy differences exist with the UR 3lap until the end of the moguls section, where only the first 2 wheelie triggers are performed and instead a regular trick is used to perform a wheelie trigger off the mogul behind the boost ramp itself (with the flip trick boost being jammed). From here, since the first mushroom was used in the same place as every lap of the UR 3lap, you can use the second mushroom to perform another zipper cut directly to the final zipper section. Immediately upon landing, the third mushroom is used to perform yet another zipper cut to skip the last turn.

The current strategy for NG 3lap is to drive 3 laps normally. The TAS starts off exactly the same as the UR 3lap, but branches off at the first turn.

Where instead of going to the right side of the cannon, you go to the left. Here, the cannon is exited regularly, and multiple first-frame hops off the slope are used to get up to the zipper, where a precise combination of wheelies and right drifts are used to stick to the left turn and maximize the zipper boost and wheelie time. Similarly, after exiting the zipper, only the first and third bumps are tricked off of. At the snow turn, there is clearly no zipper boost remaining so, following a pocket of airtime, the mushroom is used to cut this turn, and a miniturbo is charged to be released when the boost runs out.

At the "double cut", no rehop is done to stick to the edge of the slope, so the broken wheelie lands away from the edge of the road, and a bounce (and wheelie cancel) must be used to get the partial stick instead of a rewheelie. On lap 1, a wheelie is used to align for the first-frame hop, whereas on laps 2 and 3, handling is used. No neutral glides or momentum hops are used, so a 98 landing is performed instead (using nosediving for EV and a quick-enough wheelie upon landing). Significantly less rehops are done on the final zipper, and handling is used instead of a hop into reject road to exit it at the end.

The current strategy for NG flap is to drive 1 lap normally. Unlike the rest of the categories on this track, Flame Runner is used rather than Spear. This is due to the age of the TAS. The strategies used are very primitive versions of those in the NG 3lap. For example, the two tricks after the first zipper are lower, which is less optimal boost distribution. Also, less wheelie triggers are performed in the moguls section, the entire broken wheelie "double cut" strategy is nonexistent, and a double trick is performed off the final zipper instead of wrapping around it with left drifts and wheelies. The additional two mushrooms are used on the first turn and upon landing from the "double cut".

History

TODO: History of all strat developements. Section devoted to each part of the track as there has been a LOT of history here. Quite possibly more than ANY other track. Additionally, supergrinding developments, and supersliding developments which eventually led to superhopping being useful.

TAS Competitions

DK Summit has featured in one of FlaminFunky's Challenges (#3) and four tasks of the MKWii TAS Competition (Task 3 2020, Task 19 2020, Task 1 2021, Special Task IV).

Future

Known timesaves

UR 3lap

• Supergrinding from the snow cut to the moguls has been shown to be faster.
• The hop off the reject road after the final zipper (as done on laps 2 and 3) can be implemented on lap 1.
• The double cut on lap 3 is not as optimized as the ones on laps 1 and 2.
• A faster start slide exists than the one used in the current TAS.
• The run was made before full input range was available, so wheel inputs could be used to save time during any airtime.

UR Flap

• Using Wario Bike to perform WBSS on the first turn, and completing the remainder of the lap with additional superhopping, is faster.
• The first zipper cut is not as optimized as the one in the UR 3lap.

NG 3lap

• The rehop and rewheelie method of the double cut (as done in the UR 3lap) can be implemented.
• The neutral glide after the first-frame hop (as done in the UR 3lap) can be implemented.

• The hop off the reject road after the final zipper (as done in the UR 3lap) can be implemented.

• The run was made before full input range was available, so wheel inputs could be used to save time during any airtime.
