Error: G30: Z probe point index out of range

Hey everyone!
I'm trying to test the accuracy between two of my zprobes for choosing the better one, and I'm trying the script from here: https://forum.duet3d.com/topic/1291/testingresolutionaccuracyyourresultswantedzproberesults
Since the thread is locked and I don't want to dig up that thread, I'm making a new one for an issue I'm having.
When running the 36 probes 1 point script, in which I have just modified the X and Y position (see at the end), I get the following output when the script is finished:
11/29/2019, 1:36:15 PM M98 P"0:/macros/Testing/ZProbe Accuracy" Error: G30: Z probe point index out of range Error: G30: Z probe point index out of range Error: G30: Z probe point index out of range Error: G30: Z probe point index out of range
Any idea what's going on? I searched for the error message here and via google, but I found nothing. Is there another way to test zprobe accuracy?
Info: RepRapFirmware for Duet 2 WiFi/Ethernet version 2.03 running on Duet WiFi 1.02 or later
Thanks!

It could be that a single coordinate can only be probed 32 times. So Remove runs 32 to 35 and try again (you will then get 0 to 31 which probably is more than enough. I tried with 3, 7, 15 points and didn't get a different result between the latter).

The maximum number of G30 numbered probe points supported is 32 (P values 0 to 31).
BTW it's useful to run tests separately with the probe points approached from the +X, X, +Y and Y directions, to check for certain types of backlash in the positioning system.

Thanks very much for the feedback!
I found another script on the linked github repo: https://github.com/T3P3/GcodeMacros/blob/master/Calibration and Tuning/Diagnostics/Probe_Repeatability_test
Works fine now, got a mean deviation of around 0.00759 mm, seems good to me!
