first off what you say doesnt make a huge amount of sense to me.
you say you build your skill at home - and our survey says ... *EEEEERRRRUUUURRR*
you build skill through training with a coach. the biggest skill builder is infact sparring, the thing you said provides you with all the exerience.

this is why you should do sparring all the time, it builds reactions, skill, speed, footwork, ring knowlege and "expereince"

if you want to look at skill VS experience, go watch the ricky hatton kostya tsyzu fight.
or wait and watch PBF VS gatti. that will be skill VS experience in literal terms.
see which you think is more important
