Hello, I recently ran a bifacial model with unlimited trackers in PVsyst 6.8.4 and PVsyst 7.0.2 and with the same inputs the BT Limit Phi angle changed from 68.7 degrees to 79.9 degrees. Could you help me understand the reason it would change? Orientation in PVsyst 6.8.4 Orientation in PVsyst 7.0.2

I am trying to model one shade scene with two PV tracking fields that have different row spacings. I'm getting the warning: "Several tracking fields defined in this scene. Field "33.85 GCR" : Tilted Axis tracking: The parameters for backtracking (pitch, width, or inactive bands) don't match with tracking field N°1. Field 35.31 GCR will be used for backtracking algorithm." "33.85 GCR" and "35.31 CGR" are the names of my two PV tracking fields. Does this warning mean that I should model two different GCRs in two separate variants / shade scenes?
