PVcase imported trackers does not have pitch defined when going in modify object. Does it impacts backtracking?

PVcase imported trackers do not have pitch defined when going in the modify object. Does it impact backtracking? I have heard from a few industry people that it does not do the backtracking as it does not have the pitch defined (or not an array of the trackers) and all the trackers are ungrouped and are not an array of trackers
Also if I ungroup an array of trackers which was created in PVsyst near shading, does this affect the backtracking?
See the below snip for reference
Pvcase export

 

An array of trackers was created in Pvsyst and then ungrouped

Hi, if the trackers are ungrouped or defined individually, the "Pitch E-W" parameter is not important.
What matters is the actual distances in the 3D scene.
The backtracking will still work of course.
