Can any commodity etf traders/investors explain the disconnect from UGA to its underlying /RB futures.

The year high for UGA was $80.21, back in June 2022, and it currently sits at $62 and change. A drop of a little over 22%. UGA is supposed to track the daily movement of RBOB unleaded gas futures. If you look at the /RB continuous for the same period, the decline is over 35%. Is that difference attributed to the difference between the continuous /RB vs the month to month rollovers for UGA? I've never seen such a large gap in performance, to the upside nonetheless, from a daily tracking fund that is burdened with expenses to its underlying. Can anyone explain this? TIA
