Not so. On the way home from OSH I discovered we have a static leak. Opening and closing avent would result in a 300 fpm climb/descent nearly instantly. Interestingly enough the Gemini will show a climb and keep showing a climb which tells me its just a VSI. As far as I'm concerned that's fine as long as one understands how the instrument operates. In a skidding turn it will flat out lie to you. 30 degrees of right bank with quite a bit of left rudder will show a left turn.
Yes it is so...hold the thing in your hand and pitch it up and down...it shows instant gyro based pitch attitude. It will then slowly transition to VS if you hold it in one position. A change in VS will give you an instant VS indication like you saw but it definitely also factors in instant Gyro data as well.
A static leak should not cause the Gemini to show a constant climb. I would have to see this one for myself to understand that statement.
You described a slipping turn not a skidding one.
The Gemini and all of TT's ADI based products have been explained many times by TT for years now. They are not intended to provide 100% accurate indications for all of the weird positions a person can get an airplane in if they try hard enough but the indications they do provide can guide you just as well as traditional instruments as long as you stay withing their pitch and roll limitations.
If an instrument rated pilot cannot keep the greasy side down with a TT ADI type display, they are not qualified to fly in IMC with any instrument.
