I've tested "-g 72", "-g 144", "-g 600" and for fun, "-g 6192". All produce about 7.5M to 8M p/sec.

With "-G 2" or "-G 4" added in as well, i can get up to about 9.5 to 9.8M p/sec, but no higher.

Nope, I did not factor M1061. He was referring to another composite (https://members.loria.fr/PZimmermann/records/top50.html) when talking about the ECM record (not even a Mersenne number).
