This evening I found my 1000th Leyland prime. My 500th was only ten months ago! The above chart extends the graph that I posted back then. I have 579 red values found using Mathematica (from 3 October 2015 to 3 July 2020), followed by 421 blue values found using xyyxsieve & pfgw64 (from 6 July 2020 on). I have it in mind that I might actually achieve 1500 finds by later this year. It's a tough target to reach because I'll be picking all the remaining low-hanging fruit (< 150000 decimal digits) in the ongoing search and I don't believe that there are quite 500 of those left.
