The only thing that is close to games at 24 hours per move is my correspondence
games.

There are not a very big number of games (I played only 21 correspondence games
with the help of computer chess programs)
but I also gave my computer to analyze for a long time positions that did not
happen in my games and I also gave computers long time to analyze positions in
time that I was not playing).

There were cases when I gave one of my chess programs more than 24 hours but the
average time per move was probably 12 hours(I also gave them to analyze for a
long time many positions that happened only in the analysis).
