Following the 0527 devprev scoring issue I tested wiggle behavior on all platforms for the current clients.

Below are my findings, indicating wiggle differences that go beyond 2 points between platforms, most notably between Mac and the two others, windows and linux. For this test I took puzzle 1845, reset the puzzle and used the indicated wiggle power settings, wiggled until no full points were increasing.

low->med->high is reset puzzle, lwp until no more gain, then select mwp and wiggle further until no mor egain, then select hwp setting and wiggle until no more gain.
straight med = reset puzzle, mwp setting, wiggle unti no more gain.
straight hep = reset puzzle, hwp setting, wiggle unti no more gain.
straight awp = reset puzzle, awp setting, wiggle unti no more gain.

These tests were repeated several times and scores were nearly identical every time, differing only in a few decimals depending on whether or not I let them go on for a few rounds longer.

My observation is that when wiggling on a different platform at the same setting, the outcomes are different in the backbone (I used one as a guide for the other), thus changing decisions that scripts make based on score improvement. If this happens in a design puzzle it may alter the choice of sidechains or their orientation.

I would expect all clients, regardless of the platform to score equal for given settings.
