maraming magiging instances, meron sa first week ng training wala pang pops... pero sa second week meron na... or may magpo-pop, pero nde lahat.
main point, even if they don't receive pops for the week, e ibig sabihin e walang nadagdag sa kanila, meron din kahit papano, pero hindi sapat para magkaroon ng skill level pop...
they still improve, and you will further see the improvement kapag yun at yun ang ittraining mo.
sa analysis sa isang thread sa global, training three positions with one skill might take three to four weeks, pero hindi ibig sabihin na sabay sila magkakaroon, parang in the span of 3-4 week (or i think 5-6 at nga un) doon magkakaoon ng level pop ang mga players mo na tinitraining. (it depends, of course, on the trainee's age and potential).
