50 gr weight and half inch shaft length increments.
Doubt most folks shooting fingers and trad good enough to see smaller adjustments being repeatable in effect.

Really like the Gold tip weight system

But remember, you stack enough and you gobble shaft flex length, hit a wall in adjustment.

Solution then is heavier insert.

Reg alum inserts. 100gr brass inserts. And a pile of 50gr weights......should cover tuning needs IMHO
