Will multiple reviews (caused by unsynced review on phone and computer) affect FSRS?

Sometimes I forget to always sync the cards, so (very few) cards ends up having duplicated entries like this:

But AFAIK FSRS only uses the first review of the day during training, so optimization won’t be affected as long as the first review is what it should be (lapse or good).

The first review of the day will be used when training/recalculating memory states, but the card’s current state will be whatever it was when it was most recently modified, unless you reoptimize.
