Oh come on Dean... for criminees sakes... spring tension isnt increased 
until you actually increase it. Nobody said anything in previous posts 
about maintaining <<a given hammer lift>>.  But since you first mention 
it... have you ever actually tried seeing what happens to hammer lift 
for a say.... 5 gram change in rep pinning resistance ?  I havent.. and 
cant really say I know what the result would be.  But I would imagine 
(as in guess at) that you probably would not see all that much a change. 
Another little tidbit to check out tho... good fun.

Cheers

    Seems to me it is. If you increase the resistance of the pinning,
    you must
    also increase the spring tension to overcome this resistance for a given
    hammer lift.
