IRL it depends on the promotions, managers, and fighters themselves. Amateurs who seek to elevate their skills and brand might fight often, maybe even up to two times a months (Mike Tyson did this pace until his 20th fight I think).
Well, since Wen confirmed there's a fight every month, this could be a great opportunity to consider injury and potential drug abuse affecting your combat performance. Like, Ian can win with severe injuries, so he either has to back out, keep fighting with fucked up physique, or abuse "chicken and broccoli" to boost his recovery.
Would be fun if we get to see fighters based TRT Vitor and Allisteroid Ubereem lmao.
