I’m only going off Wallace’s calculator and the charts in the book “How To Hook And Launch” while Definitely not absolutes, they (along with others I’m sure) give “ideal” numbers for 60’, 330’ and so forth. I use both to gauge how my setup does and I’ve got a stack of time slips that show my various times are where they should be according to those references. I’m now running consistent dead hooking 1.59-1.60 60’s and 11.45@114 (my Mph is slightly less than what Wallace shows ideally, due to my aero handicap at the big end) What et/Mph are you expecting with the hoped for 1.6 60’?
