Replacement cost is always brake and blade.
The blade is always dead. These things work by firing what looks to be an aluminum block directly into the blade.
Assuming of course, there is no possible way that you could otherwise reliably prevent those injuries that doesn't depend on a human's diligence. That is, of course, ridiculous, but, that's the nature of this regulation. You're also not accounting for the cost of the blade, which isn't salvageable after activation, and those can get spendy.
Realistically, SawStop wants the data so it can lobby itself into being a permanent player in the market, which will, of course, prevent anyone from innovating a no-damage alternative to SawStop, which is certainly possible.
Well, the saw manufacturers could have done that before this regulation. However, they didn't. Only once staring down imminent regulation have they been willing to concede anything.
Bosch even has a license to the SawStop technology and had their own saws with blade stops. They pulled them all from being sold.
Sorry, not sorry. The saw manufacturers have had 20+ years to fix their shit and haven't. Time to hit them with a big hammer.

Realistically, SawStop is so damn small that they're going to disappear. They're likely to get bought by one of the big boys. Otherwise, the big boys are just going to completely mop the floor with them--there is absolutely zero chance that SawStop becomes a force in the market.
As to this proposed mandate... If it's mandating any safety device, and Bosch and others can freely compete without everyone paying SawStop, I'm all for it. But if it's mandating the SawStop design, or would require all competitors to pay SawStop, forget it.
Certainly reattaching fingers would be cheaper than $48k. That's a steal of a deal in the US.
In addition, last I checked, modern medicine cannot reattach nerves so you lose a great deal of functionality of your finger or hand even if you save it.

I hope I am simply missing the joke if someone would be so kind as to clue me in.
A sense of humor might cost in excess of a finger reattachment, though.
Sweat dripping on the work piece (especially NoVA in summer with AC on fritz) was responsible for a fair share of the cartridge firing without contacting flesh.
I have seen an average of about one false firing a month--generally moisture but sometimes a jig gets close enough to cause something. I have seen 4 "genuine" firings of which 2 would have been an extremely serious injury. This is over about 8 years--call it 10 years.
So, 4 spaces * 10 years * 12 months * $100 replacement = $48,000 paid in false firings vs 4 life changing injuries over 10 years. That's a pretty good tradeoff.
Professional settings should be way better than a bunch of rank amateurs. Yeah, we all know they aren't because everybody is being shoved to finish as quickly as possible, but proper procedures would minimize the false firings.
Part of the problem with false firing is that SawStop are the only people collecting any data and that's a very small number of incidents relative to the total number of incidents from all table saws. SawStop wants the data bad enough that if you get a "real" firing, SawStop will send you a new brake back when you send them the old one just so they can look at the data.
