Guide. Factors of 3 are quite persistent with the 2^2 guide, (seems to me to often last until the end of that guide) and cause it to go up instead of down, but it is still the 2^2 guide.

Full update done.
There has been a huge amount of activity over the last week.
Unfortunately there are no downdrivers and not many sequences without drivers.
I am now about to copy sequences now above 100 digits to the main thread.

Reserving 245406, 244470.

Done with 238728 - 103 digits and 2*3^2*5
