According to the 2011 Jewish survey: "Orthodox Jews and Russian-speaking Jews together comprise more than 40% of all Jews in the eight-county New York area."
Now it's possible the 42% is pretty much the ceiling among Jews (i.e. the conservative-leaning segments have maxed out, and there's minimal gain in the other segments).
40% of the population means a lower fraction of the electorate, so I would be surprised if it was just 56-43 in 2022, but Zeldin managed to improve on Trump's numbers by a substantial amount in South Brooklyn.

That's less improvement in the Jewish areas of South Brooklyn. The improvement is strongest in the Chinese areas.
