       Realistic, the bonus should be related to the skill level, and not player

  Yep.  OTOH, since you only need charisma in limited circumstances, it is 
mostly useless anyway - you go to buy/sell some items, and not apply all your 
charisma enchancing items.

  reasonable.

      Thus diff would be between 0.1 and 0.92.

      The SQRT would help to generate diminishing returns for higher levels.

  Seems reasonable (one of those formula).  However, you need to make sure that 
the overall bonus/advantage never gets to a case where you can buy something for 
  less than you can sell it.  Otherwise, the economy gets really screwed up.

      Then exp += abs(price_for_player-price_for_dummy)*somefactor.

  Presumably, that can be simplified to some extent based on just the bonus we 
are giving to the skill?

  The one oddity with this is that as player gains exp in the skill, they'd have 
a higher bonus, and thus get more exp (ignoring the other fact, that as players 
gain levels, the amount of treasure they haul back would go up in value also).

      I suggest to set the ratio for overall level to zero.

  Probably correct.

  Yep - just buy and sell (repeatedly) the same object.

  It all seems reasonable to me.
