If I were to use an uneven lie golf mat, would the GCQuad still work and generate the correct numbers?

If you have the GCQuad sitting level (not on the mat) then it will work. If your mat is giving you a downhill lie, the shot will show up as coming off lower like it would on the golf course. I think it has some sort of accelerometer built in to adjust for small slopes, but I don't know if it would be able to handle being on a large slope. -

I know this has been addressed but I'll give my example... My garage floor slopes about 2% back to front and i was hitting towards the back so im hitting 2% uphill. It took me almost a year to finally figure out why all my numbers seemed to be off from ball launch numbers to club data. Finally I had an 'Ah Ha" moment and downloaded a cheap app for my phone and laid it on my hitting mat.
it less of an issue with the shorter the clubs, 2* off on a shot launched at 30* is 6.66% . 2* off a driver launched at 15* is 13.33%
So, i leveled my hitting mat with some garage floor tiles from home depot, basically gradually building up layers front to back to get my stance and hitting mat level. the front of my mat is still on the garage floor, but the back has been raised around 1.25" or 1.5". My launch numbers now are completely different. Total ball flight is probably about the same strangely enough, that might just be operator err.Comment

Readings on a launch monitor are relative to it's own orientation. If the x,y,z angle orientation of the launch monitor is different then your hitting surface you get offset readings relative to the hitting surface.
One purpose of the internal accelerometer is to make the translation to sim programs for launch angle and azimuth data so the visual ball representation i.e. height, distance, curve etc are correctly presented. If you make the x,y,z axis of both the hitting surface and LM the same any translation problems go away. If not you get what you get.
The other purpose is so the LM can be used outdoors for instance on a range. All ranges have some designed in angle deviation from level simply to assist drainage. There is also some deviation from level due to land settling, frost upheavals etc. Since in those instances you can't level the range the LM accelerometer makes the required adjustments.
