Lightroom Classic: SDK Lua plugin to compare speed of LR of different configs help!

I want to create a plugin that would be usefull for comparing the performance of Lightroom Classic with different configurations doing operations on multiple pictures.

I already know how to code, Lua is new but not that complicated, and I play a little with the SDK and made a basic plugin to show my system info (Memory, LR version, etc).

I beleive that the best way to do this would be to inject in multiple pictures a series of operations on them, let's say:

1. Exposure2012="+1.00" (normal exposure +1)
2. crs:PaintBasedCorrections (a brush strike in the picture with different settings)
3. <crs:RetouchAreas> (Spot removal)
4. etc...

So my questions are : how can I inject those operations? :) Or how would you do it? Is there some limitations?

Current version Lightroom Classic 9.2

Latest SDK OCtober 2020 version.

Thanks.
