How do I deal with characters that spend a lot of time learning something? For example: Everyday they spend an hour sharpshooting.. Or everyday they read about something knowledgable.. How do I run rules wise their learning a skill in this way? o I just give them a experience point according to their study? So for example you get 3 XP in that skill alone?

It sounds like you're overthinking things.

All that practice and learning should be narrative description for how they are spending the XP already being awarded to them at the end of every adventure.

If they spend an hour a day sharpshooting, but ignore range-weapon skills and talents in favor of social skills and talents, then they may want rethink how their characters are spending their free-time.

kaosoe has pretty much hit the nail on the head.

All that time spent practicing is the narrative justification for the characters to improve their skills or purchase new talents when spending the XP they've earned from their adventures.

If you were to award XP for "practicing" during downtime ( not something I recommend), then I'd keep it a very small award (5 XP) and only if there's been a month or so of downtime between adventures. This would reflect that the PCs are doing things to improve themselves, but it's not a huge award either and thus won't penalize those players who would prefer to have their PCs either be taking it easy or simply living the high-life when not involved in an adventure.

OK.. I get it. This helps a lot.. thank you
