That's not what I meant, WinsingtonIII. In RTW vanilla none of my land units would receive recruits with the average experience of other men in the unit prior to it having it's losses replenished.
But in EB, with unitsize at huge, I retrained a unit of slingers of 38 men with level-5 experience (2 silver chevrons) to full size of 120 men. That is to say the unit received 82 recruit slingers fresh out of the barracks and they all had level-5 experience - they were not rookies. The unit did not loose experience when it had it's numbers replenished. So I am thinking what if I expose a rookie unit to enemy fire, bring it's numbers down, then transfer experienced soldiers from another unit with high veteracy and retrain-replenish the veterans. It sounds like a spoiler too good to resist.
