I've been comparing the Baseball Reference and FanGraphs projections for a while now. It is interesting how different they are. I think what's going on with Baseball Reference is that to get a good sample size they're looking at a team's performance over the last 100 games. As of today, the Mets are two games over .500 for that span. And Baseball Reference projects them to be two games over .500 for the rest of the season. That led to some screwy results earlier in the season, though. There was a point when the Mets had actually performed better than BR's original projection, but their playoff odds had gone down. And I think that's because the more games they played, the more games from the end of 2019, when they were really hot, dropped out of the sample. So if they won, say, three out of five, but a four out of five stretch from 2019 dropped out, the sample, and thus the projection, got worse In any case, if they keep playing well, and more and more of that lousy 2020 season drops out of the sample, you're probably going to see those projections jump.
