Gimp settings were Opacity: 100,0 and Pressure sensitivity: Opacity [check]
So, there should be no differences there between the opacity settings
in both apps.
What is it you find fishy? I used a wacom tablet btw.
The large difference between minimum photoshop settings and minimum gimp settings. I feel that if it's very different, the comparison is not very useful. Perhaps you are more aware of the exact nature of the difference; they look very dissimilar to me.
I think you can also set a pressure curve for opacity (or any other variable pressure can effect.) depending on which version of PS you have, apart from the settings which you mentioned.
If the settings are indeed correct, then, my comment on this:
PS seems to treat the brush spacing differently when flow is in use.
You mentioned time-based effects - I think PS is treating the brush spacing as a spacing through time (rather than gimp's interpretation - space) and maybe also smoothing the stroke by a factor inversely proportional to flow.
If you want more visual examples to work off of, you could look at OpenCanvas (which is not opensource, ironically. It's a Windows based paint program.) - it has a drawing method(tool?) which behaves similarly to what you seem to want.
