I will offer a perspective from someone who in a previous life was involved in the interview process of flight crew. While hours spent in a level D sim do have a certain amount of interest to a potential employer, they should be kept wholly separate and not included in aircraft totals. On the odd occasion that I saw this (inclusion in grand totals) on an application/resume my view would be...what else is hiding here or may be fluffing up the numbers. Quite frankly I wouldn't have the time or the interest to dig into it and would simply move on to the next applicant. Whether the regulator allows inclusion or not for the purposes of a licence upgrade is of little relevance to most employers.
My 2 cents, take it for what it's worth
Cheers
