Question about units with 500+ experience

[testarossa]

Once a unit has reached the 500 pt experience level that receives the appropriate bonuses and ability to over strength to 15, is there any advantage to continue accumulating experience to the 599 cap? If not the only nuance I can see is that if the unit is at a strength level of 9 I can reinforce with green recruits if at about 556 (556-56=500) and still remain at the 500 level after reinforcement. Any other possible advantages?

Since there is no answer I can give my thoughts as well. I don't think so, but I never got there, so I did not do any testing. My units tend to cap out between 400 and 500 or do not even reach 400 on field marshal. At that stage I usually get 0-1 exp for an attack. Should make more risky attacks I guess

The bonuses are always gained upon completeion of a full star of experience (100 pts). 599 is still counted as having 5 stars, so 500 is the highest worth getting.
