According to the document submitted to CPSC: Over 1,300. Finger saves that happened but not reported were not included.
Source: https://www.regulations.gov/document...2011-0074-1106 (File: SawStop Finger Saves REDACTED 10-10-2011).
The manufacturing and education sectors accounted for the most reported saves. (I don't know any school that is still using non-SS tablesaws.)
Most reported incidents required either a bandaid, a cleaning or no follow-up treatment.
If you are interested in knowing what time an incident happened, what kind of cut was made when it happened, etc., check out the document. The spreadsheet is more easier to read.
