Additionally, it's stage 1 only, so really impressive! (k = 5 × 37 × 251 × 1493 × 2203 × 9533 × 25301 × 59467 × 607147)

It doesn't have to be a particularly noteworthy factor for Stargate to be fond of it. (Reread the thread title.) Now, if we start adding sub64bit factors here, that may be crossing the line.

M3000409 has a 94.882bit (29digits) factor: 36506847546234971967385191137 (P+1, B1=15000000, B2=1530000000)
This is my first factor found using the P+1 method. The previous 36 attempts were unsuccessful. Success is diminished by the fact that this is the second factor for this Mersenne number

That doesn't diminish the success. What does diminish it is the fact that this is a stealth P1 factor. i.e. Had you done P1 to the same bounds, it would have found the factor quicker.

Unfortunately, it is impossible to predict which method will prove more effective in a particular case.
