I guess +10 Elo (max.).

Whenever I read results of people who took a close look at the end of many
computer games (which wasn't reported often), to see if and how tbs. were
responsible for the results, the baseline was that these are very seldom cases.
For example, this was examined when SSDF tests were affected by the incomplete
problem, and it turned out IIRC that although it was there, it obviously didn't
affect results at all (or at least only very few; I don't remember exactly). The
problem was solved anyway.

Nevertheless, tablebases are an improvement of course, because the engines will
most often play more precisely in the end, disregarding if the result has
already been decided earlier in the game.

Note also that when using Lust 5.04 (or any other engine) in a Fritz GUI, the
"static" tablebase access will always be done by the GUI as soon as a tbs.
positions in reached in the game.

Currently I'm not sure which one is stronger, List 5.04, Ruffian 1.0.1 or SOS.3
f.Arena. For example, see this rating list compiled by K.Wlotzka (he runs games
at 10m+10s, A12000, with 10 predefined opening variants):
