Sieving for ESP has now reached p=90P, which is where PSP and SOB had been sieved to. The PSP and SOB candidates have been added back into the sieve file and as a result of the increased task times credit has been increased from 137.0900751 to 226.4205. There's a 10% conjecture bonus, so actual numbers are 10% higher than that. As seems to be "normal", I screwed up the XML during the update, which meant that there were a bunch of "error while downloading". The XML has now been fixed and those WU's should now download properly and complete. I'm running one myself now. If they don't fail immediately, they won't fail at all.
We'll be evaluating the optimal sieve point and will give at least a month's notice of when we're planning to pause sieving. It's also possible that at that time we might start sieving for higher n's, in which case sieving will run for at least another five years.
Edit: Added sentence about the 10% conjecture bonus.
