I don't get the correlation between what VV says, what other people use and what you want to achieve.
whichever way you slice it you are going to have to start at a low charge and work up for your rifle
its a guide
shoot smaller numbers of lower charges to prove pressure rather than accuracy
no point wasting 5 rounds at 34 if you are not looking for a reduced load, you are only shooting that level to prove there is no pressure issue with YOUR combination of brass, primer, powder lot, seating depth and chamber size.
once you get into the mid range of where you are likely to approach your target velocity shoot larger numbers of rounds at each charge level
