FWIW, I emailed Pilot Credentials and asked about the instrument rating time/experience question:

"I just had a quick question regarding my profile. Under Certifications > Aeronautical Ratings > Total hours of IFR Certified (Instrument Rating) experience: Is this asking for total Actual Instrument (IMC) time or total flying time on IFR flight plans? To me, it is a little ambiguous. I guess it may be a dumb question and I assumed it meant IMC time only, but I would appreciate clarification on it."

Reply:
"Sorry for the delay, i wanted to get clarification.
This question is asking for Actual Instrument Time.
