I don't have a real answer, but your patch includes lots of completely
undefined execution orders, that might or might not be related to the
unusual scaling. You should use manymany more trigger objects. 

For example this little construct in your patch: 

  |
  [pow -1]
  |\
  | \
  [* ]

has an undefined result. You must replace it with: 


  [pow -1]
  |
  [t a a]
  |   /
  |  /
  [* ]

to correctly get the square of the inverse as you probably intended
and you must do similar triggering in the rest of your patch.

Maybe this already fixes your problem.

Ciao
