RAW Rapid LW Polygon Barrel Question

Two stand-out LW polygonal barrels come to mind...
1- .177/10.34 @915-920. 1:36 twist, prefers Slick 50 One lubed pellets. Clean it around 600-800 shots and it's happy. No fouling shots necessary after cleaning, 1st shot after cleaning goes right where it should.

2- .22/25.4 @ 955-960, 1:32 twist, prefers Gunzilla lubed pellets. Clean it around 300 shots and it's happy. Needs 10ish fouling shots right after cleaning for things to be good again.

Before I arrived at the above regimes, both needed cleaned much sooner. The lube didn't seem to make more accurate, just extended cleaning.

Generally I feel like poly barrels need cleaned more often than traditional 12 land and groove LWs. I've got a couple 12 l&gs that I'll shoot 4+ tins out of, unlubed, and not see any degradation of accuracy.
