Interesting. Here are my results. I simply added UltraSolid to my own settings,
since Vasik had theorized the parameters are independent of each other, so that
I could measure it provided I had a proper reference to compare with (meaning
the same conditions):
The default settings scored:
1 Rybka 1.01 Beta 12 32-bit 2900 +22/-11/=17 61.00% 30.5/50
2 Hiarcs 10 2850 +11/-22/=17 39.00% 19.5/50
1 Rybka 1.01 Beta 12 32-bit 2900 +19/-15/=16 54.00% 27.0/50
2 Fritz 9 2820 +15/-19/=16 46.00% 23.0/50
1 Rybka 1.01 Beta 12 32-bit 2900 +25/-10/=15 65.00% 32.5/50
2 Fruit 2.2 2850 +10/-25/=15 35.00% 17.5/50
1 Rybka 1.01 Beta 13 32-bit 2900 +28/-7/=15 71.00% 35.5/50
2 Gambit Fruit 1.0 Beta 4bx 2820 +7/-28/=15 29.00% 14.5/50
Total: 125.5 / 200
Improving Position = Slightly Optimistic,
Deteriorating Position = Much More Pessimistic

Unconclusive, obviously.
I should undoubtedly try isolating the Improving Position setting from the
Deteriorating to see if one is better than the other, and being compensated, or
whether together they don't really offer any special edge. And of course,
UltraSolid should be tested alone in my own testing to confirm there is no
interaction between the parameters.
Soundness = UltraSolid
Improving Position = Slightly Optimistic,
Deteriorating Position = Much More Pessimistic
1 Rybka 1.01 Beta 13 32-bit 2900 +26/-11/=13 65.00% 32.5/50

Note that Gambit Fruit was tested at 4m + 2s and the others at 3m + 2s.
