I don't have the Israel numbers, but UK data shows 137 confirmed cases of reinfection out of 5.2 million first-positive PCR tests, which works out to 0.003%, see charge on page 18, https://assets.publishing.service.gov.uk/government/uploads/...
The original spring 2020 outbreak in the UK was huge, affecting a sizable percentage of the population. However at that time PCR testing was nowhere near scaled up to the point that all of these cases could be tested.
Therefore if you were infected in the first wave, recovered, and are now reinfected 16 months later you probably aren't going to be one of those 137 because it's quite unlikely you were PCR tested the first time around.
That's not to say reinfection is super-common either, but it's probably at least an order of magnitude (or possibly even two) more common than that raw percentage would suggest. In other words, you've produced a statistic with zero significant figures of accuracy.
