It depends on the slope of the mainline. For 3/4" mainline, Cornell's Maple tubing and vacuum notebook says:
<5% slope = 400 taps
5-10% slope = 300-500 taps
>10% slope = 300-600
So, around 400 is a good average number if you don't know your slopes.
With that said, our mainline are all 1”, with 130-250 taps on them. Minimal cost to over size and not have to worry about high flow day issues on the 230 tap line. We did use some 3/4” line on a branch from the 1” to pick up around 60 taps on a side hill.
