Correct, if it helps for future references, I can add the info as a comment
in the code.

Agreed. But I don't want to make any assumption on the values to throw
this warning. We can silence it to debug in the future if it gets annoying
on some real systems where it doesn't matter much. I just want to keep
it to give f/w a change to correct/adjust it if they can.
