Bowser's Haxdash

Bowser's Haxdash is frankly a little impractical considering how he has such an easy alternative for refreshing intangibility with his Ledgehop Doublejump Intangibility Refresh. I found a nifty setup for it that has a frame of leniency for the controller polling, though, so I thought it wouldn't hurt to post the setup to potentially grind it out later.

Basically, you need to drop from the ledge after your 8 mandatory cliffcatch frames that start any ledgegrab. On the frame immediately following the drop from ledge, input a doublejump drifting towards the stage, and hold that drift for 16 frames. Then, on the 17th frame, you roll the input from drifting inwards towards the stage to down and very slightly backwards towards the ledge, and on frame 17 you hit the trigger button to start an airdodge. Then you have 3 frames of airdodge before you become grounded, then an additional 3 frames of sliding on the stage, 2 airborne frames after you slide off before you can fastfall, then you input a fastfall and you'll grab ledge for free while retaining full intangibility. The exact frame data is as follows:
