Calculating Returns & Compounding - Need a MATH Expert

In the attached, I have 2 different calculations for a compounded return. Looking at cell D9, I don't think this approach is right as it doesn't seem to take the quarters into account. I think cell F9 is correct though as you are using time.

Can a math person shed some light on the different approaches?

F9 is only correct if you have some very odd accounting parameters

Perhaps you could explain what you're trying to do?

I am trying to get a compound, since inception return with those 6 or 7 quarters. I was presented with the calculation in cell D9.

Cell D9 doesn't seem to factor in time at all though whereas F9 does.

What?

An average return? Are your quarterly returns per quarter? Normalised? Annualised?
