The Player Guide is outdated anyway. Especially those limits in race descriptions are related to units noone understands.
Example - Stonebreakers and Hammerwielders: "Limit 8th rank for magic. Limit 8th rank for martial arts." What are "ranks"? Magic has levels for skills and realms for spells, the current maximum realm is 5 - for spells of the second realm you need minimum level 20. If "rank" would be equal to "realm", there would still be enough overhead not to complain. If "rank" was equal to "level", it is very obviously not an implemented limit, or dwarven grand-mages would not be able to exist.
The Player Guide contains only "skill limits", but no "stats limits" per race.
