Perhaps the rating scale should not be linear, there is no question in my mind that krppkrp is the most important in the 7 man set , just as krpkr was the most important in the 5 man set,. It is the most important due to the "trickiness" and the frequency. I was doing some testing on EGTB's and many of then are solved by today's engines without any tablebases. krppkrp is the hardest for any engine to solve without egtb, based on over 30 years of observation ( and some testing ), intuition and some conjecture, ymmv.

krppkrp is a must have given its frequency plus I believe its the only one to have a book written about it. The book doesn't seem to get much mention here but if you bought John Nunn's 5pc books this one is worth getting too (IMHO of course).

I'm just going to put this out there as sort of help post for those that are wondering about the most economical way to use 7 man syzygy. I'm sure others have some pretty good suggestions as well and please feel free to share. First, there is real no need to get all 20 GB or so to benefit from 7 man syzygy. Fromm a practical standpoint , about 6o files (rtbw and rtbz) are all you need to get started , provided you have the all of the 6 man syzygy. Only RTBW are used during search, but the RTBZ files are needed, and all the tables that can be reached through promotion and the corresponding DTZ tables to play out the mate reliably. For this purpose, it assumed you will place the others files required to play out mate on an HDD drive.

So we have an 1 TB SSD drive, we have copied all of the 6 man rtbw and rtbz (recommended) onto this drive and we have roughly 800 GB left. A portfolio of the 7 man rtbw files listed below, will capture nearly 80% of the 7 man endings reached in human play.
