Default Idle and A/C Control on MS3-Basic

I wanted to verify settings and hopefully improve some anomalies at idle.

This is what I found:
In going through Brain's Closed PWM control adjust procedure, I first ran into setting the PWM for full open was running up to around 5000 RPM. Hence, I did turn in the idle screw about 1/2 turn. Still, to get to 3500 RPM I was at 75% duty cycle (which numbers I used) but was afraid what 100% would send the idle to.

On the closed side, I got 650 RPM @ 10.2 Duty Cycle.

Didn't really get too far with really setting the PID, so I just put it back to what was there from Reverent.

Question: Should I care that I could not find the true full open RPM?

Second, in going through the procedure, I tried to set the A/C idle-up to zero. It still idled up by about 200 RPM (I did a power cycle). Then I set the A/C idle-up to "NO" and the result was no A/C clutch engagement at all.

Question: Is that a bug?
