Where:
Cx = Coins purchased at time x
Px = Price at time x
This simplifies a little to:
(I1 + I2 + I3 + I4) / (C1 + C2 + C3 + C4)
Where:
Ix = amount invested at time x

I got it now. Total amount invested/amount of bitcoin owned, just like I do to find my average cost of stock shares. What threw me off was owning a little over 1/10th of a bitcoin, I've never dealt with stock share fractions but it makes sense that it's still calculated the exact same way.
