Another really important factor to consider is sump design. Skimmer chambers should be designed to trap lighter organics with a baffle and be sized properly for the flow rate of the sump. Ideally organics should float in this chamber just like they would in your display and become trapped with the only exit into the skimmer. I've seen many sumps where water exits the skimmer chamber over a baffle instead of under for example, this setup would probably benefit from the slowest possible flow rate.
At least that's how I look at it.

I'm with you: I think flow rates are irrelevant. So, whatever I did to make the skimmer more efficient was purely luck IMO. And like I stated above, 3 days could be just coincidental.
