Gribozavr:
My sievingdepth notes don't make as much sense now as they did in July, but my estimate is at p=1.5T, you're finding a factor about once every 2 hrs 10 min, with the efficiency cutoff at about 2 hrs 20 min. Thus, you've stopped sieving at almost exactly the right point for your chosen kvalue.
If you have recent data about how often factors are found, I'd like to hear how good my estimate is. factors are not smoothly distributed, so anything from 2 hrs up to 2 1/2 hrs per factor in NewPGen will make me think my guesswork is accurate.
