Yeah your number's surprisingly (to me) actually not far off.

Use of Tasers varies pretty widely from department to department -- according to [1] the Richmond County SD reports about 0.053 uses per officer-month, Miami-Dade PD about 0.0074 uses per officer-month, and Seattle PD about 0.056 uses per officer-month.

Extrapolating the RCSD value across the US, with over 800k officers total [2], it comes out to about 43k uses per month. Given the ~200 months over which this data was gathered, that's 9.2M uses, which makes the 276 fatalities only 0.003% of all incidents (as a best-guess).

Obviously that in no way implies Taser's behavior was ethical; but it's actually a surprisingly low fatality rate for a weapon still considered somewhat lethal.
