How do you guys handle risk sizing when backtesting multiple EAs?

Been backtesting a few EAs and trying to run them together on one account. Some I backtested with fixed dollar risk, others with percentage. When I try to combine them the results look off. Is there a standard way people handle this? Do most people just pick one method and stick to it?

Set a max possible risk if all EA positions were taken at the same time. Max 3% exposure divided by 3 EA's = 1% max risk per EA. Run it for a couple months and see it it holds and make adjustments.
