How many times do you process your plant matter (ice water extraction)

Just curious as to how many times other people process their trimmings when making ice water hash....

I use a bubble now machine, and I used to do 2 extractions (running the machine for 15 minutes each time)..Ive since cut that down to just one 15 minute pass in the machine because the material from the second pass always seemed to have more plant matter in it, and any more I prefer quality over quantity.

Also, would you guys agree that the majority of the trics come off in the first pass?

I do 2. One 8 minute for quality. Second 15 minute is lower quality but gets 'the rest' and isn't too green yet.

I agitate hard for a bout a minute, then filter. After 10, 12 such gos, my recovery drops to almost nothing. cn
