Which affects your formula more? Going from +1 to -1 or going from +10 to +5. In my opinion, for the ideal formula the first one should have more effect. Because +10 to +5 happens all the time when someone simplifies his position and goes for the easy win rather than most "correct " one.

The expected score drop from +1 to -1 is 42% and from +10 to +5 it's only 4%, so going from +1 to -1 affects the formula much more.
Wow! This is very nice then.
how about a=0.9 or 1.2 or 1.9
