No problem from me. I spent sometime on it earlier today as well, took me a while to work out what I'd done originally.
I've sent a copy through to The1 to have a go at breaking it before I posted it up.
Key fixes:
1. Ensure first value of table is greater than last value of previous table.
2. Fix max maf value to 510g/s.
3. Fix maf graphs of before and after
Has a couple of macros to work through with a number of loops, so can be a little slow. Will post it up when I can get the kids of the computer, will also be interested to have a look at yours and see if I can "pinch" any ideas for improvement.
