Malcolm...I use the regular snap roll function on the spring loaded switch to get the deflections in the ballpark while test flying the maneuver.
Then, I use a digital inclinometer to measure the surfaces, then set up the stick logic and adjust the AFR when the condition(s) are active.
After that I go back to the snap screen and set the master switch to off.
I like to leave the set values in the snap screen in case I need to go back to the switch for some reason.
Caution...be sure to set the master sw to off because with the logic condition activated.....the snap switch can overdrive the servos and perhaps damage something.

Jim....I too have flown flights on the wrong condition....I'll see if I can figger a way to add an audio alert to the spin switch.
