Does anyone happen to have their scaling and latency numbers for DW850s?

 

Someone has to have done this before.

I can use the direct latency numbers that came with them, but they only go 7-17V, stock was 4-18+V...

For scaling I've read you use 90% of the rated value, but not everyone seems to agree on that.

Obviously I'm looking for a good starting point, and then adjust from there based on fuel trims. I just don't want to be so far off base I can't get started.
