I learned my squonk technique from a bumble bee somewhere along the way... that and with HOURS of countless practice

It hasn't failed me yet. I do not take my drip tip off and I do not blind squonk till I hear a gurgle. Here is the method... be careful, it is
VERY complicated.
If bottle is full, squonk for a count of 3
If bottle is less than half full, increase to a count of 5
You can taste when it wants to be re-squonked... I don't take super long draws so I don't get dry burnt cotton hits. You just begin to taste the cotton a little... and then you re-squonk.
Ive only been using my Reos for a little less than 3 weeks now, so I am not as seasoned as the others. I can tell you though that after a fresh squonk I can get 4 or 5 hits and can INVERT my Reo with no leaking!
I haven't had juice on my hands in the last 3 weeks.... and it happened daily (multiple times) when I was dripping on a tube mod with an IGO-L
I hope this helps!
