Lvl speed: stam vs energy

stamina: i tested stam and it seems to have a 2,5 exp-per-point average. (over 100 attempts)
considering stam gets you 2stat points we can assume every point spent in stam worth 1,25exp.
energy: there are 3 factors:
1) quest value (exp-worth/energy): it usually is 1.3 , going from a minimum of 1 to a maximum of 1.5 (the more you get thought the stages the more it grows, surpassing 1.5; same for boss fights that get over 2.0)
2) repeatibility of quest: you can do quests a limited number of time before it is complete (and you must finish the stage before resetting, activity limited to once per level).  
3) value of a stage: more then considering single quests we should consider stages as a whole, calculating the average value of every quest with their own weight.
tested #First stage-3rd area-Hard mode: weighted average: 1,32 exp per energy point.
however it must be considered that exists 2 buffes to actual exp received by stam: haste and quicken mind. it s been calculated that the value of exp gained with those buffes contemporary active  is near 1.32. plus, my actual average could be wrong and should be filled by more data, so the average value of exp got from stam may be highter or lesser.
