That's quite interesting. I moved from one big 4 to another, and i saw the bulk of the NQ to 3 PQ associates getting average increments per 12 month period of about $650 (previous firm which used to give the lowest base pay in the big 4) or $1k increment (current firm) - averaged over the first 41 months (August call to the December 3 years later). There was, however, a more significant variance at my previous firm. The increments also tend to get larger around the 3-5 PQ period (but greater discretionary adjustment).

Also just heard that R&T improved the salary for 1 & 2 PQE to approximately match A&G and DN.
