EK2_ALT_SOURCE with GPS Blending

Quick question about EK2_ALT_SOURCE. Now that I am using dual GPS receivers with blending enabled, would I be able to obtain better altitude hold by setting the source to GPS instead of baro?

I doubt, GPS altitude is quite inaccurate, and its inaccuracy caused by atmospheric conditions, so the readings will be quite the same from two gps located side by side, blending them will not beat baro… (that is my two cents)

Thanks. I will leave it alone for now. Looking at the possibility of lidar-lite to improve altitude…

No, GPS height error is very large, even if you have two GPS is not OK, the main height sensor can only use barometer, or you have high-altitude laser range finder.
