Make sure you are not confusing earning rules. There are different rules for RDMs (award miles) from the rules for PQMs (status miles)
When flying UA operated flights, PQMs paid flights credit to UA MP are at least 100%.
When flying OZ operated flights, PQMs paid flights creditto UA MP are at least 70% (G, T, V, W) and all the rest are 100%.
As far as RDMs, the G, T, V, W fares on OZ operated flights are 50% and K, Q, S fares are 75% -- but this is RDMs not PQMs.
