While trying out Bounce % attempts I felt that it was barely faster to bounce on the first beans head before jumping onto the second floor so I thought I'd try and incorporate it into a run of regular bullets.

it probably needs to be times to the millisecond to see if its faster so I could be wrong but in general I think its easier to do than the technique used in the WR run.

This is indeed faster than the WR strategy... However only by 2 frames in 30fps or 1/15 of a second saved (0.066666666s). So really there isn't a noticeable difference in the times however this strat is, in conclusion, faster, and as you said, "it was barely faster".
