You need to read your own posts, and remove your assumptions. I do Control at 2-4 major (200+ fencers) tournaments a year. I am not inexperienced. "Tens of thousands of masks per year", eh? Um, I know armorers work harder than almost anyone else but just no. I test my mask once a month. I do not know if this is too often or not enough. It's just a habit. If I do not test my mask for 2 months I do not feel like I am risking my life. The legal argument is an interesting one. Testing a mask does not remove the threat of a lawsuit, however. A standardized guideline on how often a mask should be tested would give more legal weight to the test. You can't have a standard without data to back up the standard. "Well these guys over there said once a month is good" is not actually data for a standard.Testing is. Those people "with very little training" testing masks risk 1) your mask and 2) passing failing equipment because they are inexperienced. The largest Division in the USFA currently does not punch test masks before each tournament. There have been 0 fatalities and 0 injuries resultant from this practice. Fallacies only apply to academic debates. In engineering (ie. the real world) we can refer to things as 'close enough for all intents and purposes'. I'd like to see where I said not punch testing is more safe than punch testing. I'm betting you just made it up, because you can't be bothered to read. What I did say is that you can't prove punch testing once a month is statistically safer than punch testing twice a year. Which, by the way, you can't.
