Those are not the results I was expecting.
The first value, 2100 only drops by about 100 when the 2 position sw is thrown, but the middle value drops by almost 500. Then the last value only drops by about 100 again.
Thats also makes the values not go in sequence the way I was expecting. You will have to flip the 2 pole switch once for each jump which would be confusing.
Id start by trying to get the first offset value for the 3 position switch to be the correct value to give the first desired pulse width in sequence - thats with the 2 position sw in the 0 offset position.
Then adjust the 2 position sw offset value so that when its thrown, you get the 4th value you are seeking.
Then move the 2 position sw back to zero and set the second position on the 3 position sw to give you the second value you want.
Now go back and throw the two position switch and see if it gives you the 5th number in the sequence.
repeat for the final values.
