A more accurate velocity will just give you closer starting point

Are you saying dont use one just measure drop at known distances?

Cant beat actual real data

Now I have a good spot out to 1km I may not end up getting one then. Much more fun to get real data!

A way i found good was to zero at 100 and then shoot a group at say 300 without dialling at all. Measure the drop, tutu with speed in the ballistic app to get the same drop then check at further ranges good to go

Xactly wot I do!

more information is nice to have but they're not essential to shoot at the distances OP is talking about.

measuring the drop and working out the velocity and fine tuning it as you get further out with more measurements with comparisons on a free phone app is plenty good enough . . your going to have to shoot out to those ranges anyway to validate chrony readings
i have a chrony but seldom use it . . . shoot and measure the drops to me is kinda enjoyable . . but then i only shoot medium range hunting rifles with one powder type at a time, super low ES don't mean much to me, good enough for the job is all i require
