So in 4-2 everyone knows about the 3 bump (this is not including 2 bump and blazeit cause those would be faster than this) I was looking for time saves and I tested to see if 3 bump or the old method of going up the vine was faster. With 3 bump, I left the stage with a 354 and with the old vine method (the intended way by nintendo) I left with a 356. Don't know if people knew this, just wanted to share it

The vine method indeed has the higher ingame time counter, but for speedruns the time spent playing is measured by a clock unrelated to ingame time. The reason your wine climb way is slower in runs is because the animation of the wine appearing and mario climbing it takes much longer than the time it takes to go down a pipe.

And yes, people know this, it is even mentioned in the video about 4-2 speedrun history.

And in 99.99% of the cases such a simple thing already has been checked in a game this optimized. If you think you really found a timesave, record yourself or your TAS doing it and then play that video along the human or TAS WR for that level. Then it's really easy to see if it's faster, and if it really is it's a quite convincing proof assuming no cheats.

alright thx
