This is of course true. On the other hand this is impossible to program.
One should create a "command file" with multiple (lots of) entries with
the history elo ratings of one player. I would say, mission impossible?

Secondly there is another group of users who wants to have ONE elo for
every player in the database. Quite a problem for developers to please
both groups.

Future REBEL databases will be released with elo ratings based on the
history of a chess player and his career. If you are not in (this)
group-1 DBUTIL 2.5 offers you the possibility to switch to group-2.

I don't know how a better solution can be found to please both groups.
Oh yes there is of course but then I need a list of the (let's say)
world's 1000 top players and their elo career through the years.

If somebody makes such a list for me it will be my pleasure to change
DBUTIL 2.5 accordingly.

Example.....
Kasparov,G=1977=2500
Kasparov,G=1978=2530
Kasparov,G=1979=2570
Kasparov,G=1980=2630
and so on.
And for 1000 players.
