Firefox I have some questions.

1) When you look for a wheel with good conditions, do you stand next to the wheel and observe the deflector hits to determine the dominant drop zone - if yes then for how many spins in cw/ccw direction

I try to get about 50-60 spins in each direction

2) When you estimate the ball speed, do you predict at 6 5 4 3 2 1 laps to drop and is it common that they say No More Bets early so you can not play?

I try to predict about 6 spins out and bet 4 to 5 spins out. They'll only call early if they suspect. It has happened but not common as I keep low profile

3) How large view do you have of the wheel, 25, 50, 75, 100%

To start with 75 to 100 but I can then narrow that down to 25 to 50 when I know where the DDs are. It's not worth playing a Wheel with 3 or 4 DDS so you generally only need
about 33% view taking in the 1or2  DDs

4) How do you bet peaks when the ball hit half the wheel?

Some peaks last half the wheel or more on low profile wheels. Just predict the peak centre and don't bet in the shadow (negative peak)

5) What is most common 2 or 3 dominant drop zone/deflector hits

I would say 2 then 1
then 3 then none. But if it's 2, sometimes 1 will be dominant from c and the other dominant from cc. But I only play 1 Dd or 2 if it's direction dependent or only play one spin direction but either way I only bother if I'm 75% certain I know where the ball comes off.  Also ideally the ball drop time from predection, usually about 9 seconds is a multiple of rotor speed. Eg 2 rotations on a 4500 ms rotor or
3 rotations on 3000 ms rotor or 2.25 rotations on 4000 ms rotor. That way I can check I am getting the right spin or if conditions are drifting.
