Definitely a lot of room to save time here - I just got a ~1:02 but I forgot to grab the one leaf from 1-1 (I think I was trying to test if it's faster to just do all of 1-4 actually, still don't know which is faster). Neither of those leafs take more than ~3-4 seconds, so sub 1:10 is very possible and maybe even sub 1:05
