What I would like to ‘request’ is that the get_histo_range function, which is 10 bit, returns the actual count in the requested range and the total count. That is, rather than an integer percentage.

Since rawop histo already provides access to total counts, I'm not really inclined to change get_histo_range.
@pigeonhill - take a look at the drtest.lua script in the distribution for ideas on using the rawop system.
I have, and as you say, it’s more complex to understand how to use it.
As this is RAW based, can assume the resultant histogram is linear, ie a gamma of 1.
I think I understand the xstep and ystep, but could you confirm that if, as you have, you use an odd number, ie 15, that means you will average the exposure over a 15x15 sensel area of the CFA.
Plus, do I assume I can only use the raw histo after taking an image
