Actually, there are 2 methods of that jump. Vertical jump is slower, but there's also some kinda oblique jump and that's probably 0"30 faster. However, 2 seconds are safed not because of this jump but because there's no need of chasing the hole anymore..
erm, wanted to psot pic, but "The requested file upload failed. This is either because it was not in the correct format, or the file size was larger than that allowed. Please check the file you wish to upload and try again." error occures ;)
