In reply to dale1968: What exactly constitutes a "reverse grip pull up"? In a pull-up, your hands are pronated (ie facing away from you), whilst in a chin-up, your hands are supinated (facing towards you). Chin-ups are generally easier than pull-ups due to the additional bicep activition involved in the movement.
I don't really follow what you're asking beyond that though, sorry.
In reply to dale1968: Ah, right. That depends on what kind of hold you're using. A bar would probably be marginally easier, but I wouldn't imagine there would be a while lot of difference in the actual amount. Maybe one or two at the most? It depends on the quality of the holds though.
Also (although you dont seem to be doing this) there is little point trying to train finger strength and pull-up strength in the same movement a lot of people are tempted by the two finger pocket pull-up, but its better to train for strength at maximum weight rather than some compromise between your dynamic contact strength and trying to tire your large back and arm muscle groups
