Tks for the reply...
I'm a hundred percent sure that my patch is right!
I've done r-hops in several guns...
Actually i have a different approach which ensures a 100% well done patch.
I use silicon hoses, and these silicon hoses have an inner diameter of exactly 6mms, so, all i have to work is on the out side.
In order to ensure the outside is perfectly flush with the barrel, i cut my hose to lengh, insert it into a 6.5mm machined steel mandrel, and spin it on my lathe and cut dowb the external of the hose to 9mms.
When i remove the hose from the mandrel it has the exact diameters of the barrel, either inside or outside.
All i have to do now is cut the hose to fit my barrel window, which of course is also made on the lathe.
So, i can garantee if i make 100% patches all of them will come perfectly equal everytime!

Most likely problem (I'm talking 95% certainty) is you didn't form the Rhop correctly. Double check you're using the proper (flat) nub to put pressure on the Rhop, and try re-forming the Rhop patch.
If the patch is formed properly, and you have a +-30fps inconsistency, you should see the BBs have a more random amount of hop on them, but still fly very straight.
If the patch is not formed correctly, expect to see a lot of left-right inconsistency as well as random amounts of hop applied.
At 1.8j with .30s, expect to be in the 85-95m range with a properly made patch.
At 1.8j with .36s, expect to be in the 95-105m range with a properly made patch.
The downside with Rhop is it that its performance is entirely dependent on the skill of the person forming the patch. I don't want to discourage you, but maybe you should try flat-hop instead? Very similar results, but significantly easier to do.
