old library scenes, v3>v4>v5

[finalight]

Any tips on params to alter to make decent use of previously dialed in sims without having to RnD from scratch? A lot of these were months of RnD and don't have time to re-engineer.

Basically looking for info to be able to resim and get close to the same result:

old ffx v3 sims but simming in ffx v4
-and-
old ffx v3 sims but simming in ffx v5

For example: multiply fuel expansion by 3x, etc.

Thanks!
