Tension per cent PR

[jonathan stuchell]

   Hi  all

    So since its 0.1%  instead of 1%, therefore it would be not 400 lbs 
change in tension per cent but 40 lbs per cent change?   and if the change 
is 10 cents it would be 400 lbs increase.   That sounds right to me, let me 
know.  thanks Merry Christmas!
