I would include Magic items in the CR calculations... a simple version would be "If 2 or more players have AC boosting magic items add 1 to the groups effective level, if half or more have attack/damage/save boosting intems add 1 as well"
then again I would add "if your party doesn't have someone that can heal subtract 1 level"
