The number on there isn't sealed INDICTMENTS. It's sealed PROCEEDINGS. It says it on the spreadsheet. Anthony Weiner's laptop was one that was unsealed.
But sealed proceedings often lead to sealed indictments. And each indictment can name many people. One that was unsealed was for 7 people connected with NXIVM.
I've heard the argument many times that the anons keeping track are not doing it right, but Q confirmed it a while back. I think if it was way out of bounds, he would have said something.
