Hereflow tuning

Who here has experience getting a really good hereflow tune? I know that flowhold isn’t really usable (according to Randy) so loiter is the way to go. What I’d really like to do get the aircraft to lean a bit more on the flow sensor. What other things than FLOW_NSE should I play with? I’ve tried quite a bit to get the graphs to match up by changing the flow scaler but it doesn’t seem to make much difference.
