I'm not expert in jousting, but did they ever really train against each other? I know about the different stationary targets they used to train against, but since I thought jousting was a reasonably dangerous activity I always assumed that "live" training wasn't common.
Pretty sure they must have. Stationary targets are crap after all.
Besides, same thing could be said for sword practice - or that it was more dangerous that jousting. But we would assume they would blunten their lances and not leave the pointy bit
