Euh... It went down (no suspense anymore) from:
__Re-applied formulas to all tables (in 33.32 s)___________________________
to:
__Re-applied formulas to all tables (in 0.21 s)___________________________
Well, that's an HUGE improvement! I couldn't believe my eyes...
I'll let-bind this variable in my above function, so that I don't have
to hardcode this anywhere...
Thanks a lot!
