Based on Soviet archival data, 335 Soviet MiG-15s are known to have lost (all causes).

US F86: 184 were lost in combat (78 in air-combat, 19 by Anti-aircraft gun, 26 were "unknown causes" and 61 were "other losses") and 66 in incidents.^[62] 

Total loss 250 aircrafts, 31% in air-combat. Or excluding the 19 downed by AA guns, 78/231= about 34% air combat loss.

If you follow the same math, the Russian loss in air combat would have been about 110 aircrafts.
