it takes a short 18yo being single position trained with a level 6 trainer 2-3 weeks to get a pop in JR
if ur training guys in 2 position add 50%
if ur guys are old like someone said around 25 at least double that
if ur guys are capped triple that
if all 3 ur guys would expect 2 get a pop every 27 weeks
maybe u need 2 do something different
