It is very possible the circuit works just fine as is. The computer model
is just a guess without any testing to see if it is correct. Maybe tonight
I will get a chance to hook some stuff up and see if the model is real or
just a bunch of balony. These models always have to be tested to be sure
they are correct and I would not be surprised at all if this is one case
were it is far off. Only true measurements and testing will tell. I am
also using 1/4 HP motors which may or may not make a difference. I took
some scope measurements of just the motors the other day:
