Default FFB...almost done

New development.
First, Logitech profiler is a no-no.
Regarding FFB, I got it, finaly. The multiplier of Overall and
Spring/Damper must be the same for different Overall positions. On my system
it is 46% (100% Overall x 46% Damper/Spring = 46%). This means that those
three can be 100/46/46, or 46/100/100, or 92/50/50, or 50/92/92, for
whichever strength of Overall you wish. The most extreme on my system is
31/148/148, or 148/31/31.
How to find it? I found it using F1 car, which has nice, clean FFB
forces. At that time Centering Spring (unchecked) was at 100%. I simply ran
equall Overall and Damper/Spring, all the way from 0% up. When I reached 68%
(the settings was 68/68/68/100) I had balanced FFB. Above that it was too
dampy, below that it was too springy. Now I am using 100/42/42.
Centering Spring is very interesting. Now, that I've set up other
things correctly, it is easy to find the correct Centering Spring. I still
didn't have time to find the right one, but it is somewhere around 70%. I
will use very "shaky" (this time) FFB of Cadillac car. It is good because it
swings all around, and Centering Spring keeps it, well, centered. This Twin
Montegy West track is very good for this.

Hm, interesting thing happened. It looks like Centering spring is
92%. Interesting thing is that 92/50/50/92 feels much better than
100/46/46/92, or 50/92/92/92, or 68/68/68/92. It looks like 92/50/50/92 are
THE settings, but I have to test other options also, to see what is really
happening.
--------------------------------------------------------------------------------

Hm, wrong again, : ).
Overall should be above 100%, probably somewhere around 130%.
Centering Spring should be 100%.
Spring/Damper should be below 50% on my system.
--------------------------------------------------------------------------------

No, it looks like the above was right (Overall x Damper/Spring = 46%
on my system), only Centering Spring should rather be 50%.
Now I'll repeat the whole process with CS at 50% and see what I get.
SRF car is good for that.
