> They've changed the way the calculate SI now

This is nonsense. Who is “they”?

FINRA and the SEC require brokers to report short interest data twice a month [1]. These are share aggregates. FINRA then provides those data for U.S.-listed companies to the exchanges, who publish it. None of those exchanges have changed their publishing methodologies in years.

"They" are the data aggregation websites that post shares SI.

FINRA and the SEC have nothing to do with the actual calculation of SI that various websites report.

S3 SI% of Float = Shares Sold Short/(Float + Shares Sold Short)
