My 1500th Leyland prime find

This morning I found my 1500th Leyland prime. My 1000th was only eight months ago! I have 579 red values found using Mathematica (from 3 October 2015 to 3 July 2020), followed by 921 blue values found using xyyxsieve & pfgw64 (from 6 July 2020 on). Compared to my graph for the 1000th, everything is compressed: horizontally by the addition of eight months, vertically by the addition of eighteen integers ranging from 300000 to 301441 decimal digits and two more composed of 386548 and 386561 decimal digits.
