100 yd hold question 50 cal RB

I haven’t shot RB in a many years. But back into them due to a friendly club shoot.
My target load is 60 gr Blk Mz. .015 lubed OP Patch / .495 RB w .010 patch.
The .015 OP patch really helped and was a game changer for accuracy. Thank you IL.
Lube is IL’s 50/50 Nasa /Peanuttery oil. (lol) Per our host.
My TVM is dead POA on at 50
My GPR IS 1.5” high at 50.
Suggestions / idea of hold needed for 100? Drop estimate.

It will be pretty Flat to 100 Yards. In short, if you are dead on at 50 yards it won’t change much to 100 Yards, you will likely be an inch or so Higher
