Hmm, from what I've seen it's more like 2 to 3 times the number of matriculants. (Usually closer to 2x)
So if there are 130 matriculants, then they're likely going to accept 260+ as many will end up matriculating to another school. However, with things being virtual this year, I wouldn't be surprised if more people decide to attend all of their interviews rather than dropping them after acceptance at their top choice. If this is the case, then they may have to accept even more students. Disclaimer: I'm no expert and I may very well be wrong haha.
