It depends a lot on the period (and I think you didn't include dividends?).

  1 year:   SPY  +15%  -  UPRO   +2%
  3 years:  SPY  +37%  -  UPRO  +33%
  5 years:  SPY +110%  -  UPRO +325%
Since 2016 is in line with the x3 promise. Since 2018 or 2020 definitely not.

Good catch, I forgot dividends.

Interesting that the last year performance was so bad - I think that stock market drop back in March and the general volatility / reshuffling since then must have hurt the leveraged strategy.
