Flavor Punch Pluerry

My googling says this tree needs about 300-500 chill hours.
Anyone has an opinion on this plum? I have tasted a small pluerry from the farmers market, I liked it, but I ordered sweet treat pluerry which is a late plum, I don’t think it’s the same as the one I tasted at the farmers market.
I’m thinking of replacing this plum with my Emerald Plum, it has flower buds this year, but it also has 600-700 chill hours which I don’t have, unfortunately when I bought it I didn’t pay attention to the chill hours.
