All jokes aside, Philo poses an interesting question. I'm not sure there is an answer to it though.
Compared to the streets, he can certainly endure much, much more than his non-healing peers. Whether that means 20,000 punches, or 200, I don't know. It is more damage than a street could reliably expect to inflict over a normal fist fight though.
Thor and such, I don't know. He was still conscious after 7-8 WWH punches, albeit ****ed up. That's about as solid a starting point as any as far as herald strength goes.
problem is he has been ko'd by much less than 8 punches from wwh so finding what a reasonable average is for him is extremely difficult. in some cases i'd say yeah, streets would wear themselves out first, but other showings would indicate they COULD not him out, or hurt him sufficiently to get to the point where he could be ko'd or incapacitated long enough for a forum win. pressure pointing him for wins is a viable option for some high end streets as well. which is why i don't think it's a an automatic given he can beat the best street guys.
