Subject: Email chess/ correspondance chess (engine perfection?!)

I play email chess all the time, aswell as blitz games on the net.  I also play
engine matches online and this came across.

If someone were to play an email game, say a Grandmaster vs Me, and I was to use
a computer, and the return move time was say 5 days a piece.  If I were to keep
Shredder 8 on Infinite analysis for those 5 days per move (say i keep the cpu
very cool and i give it a few hours of break)

would shredder 8 play a perfect game? or near perfect where the gm would have no
chance without the assistance of another computer?

I know that the longer the time control the better for the computer but to what
end?

with 5 days per move, that is 120 hours,(7200min)
using the starting position as a bench mark for depth vs time, (where shredder 8
goes 1 more ply after it doubles its time searching)

I calculate on my athlon 1700xp that after 5 days shredder 8 would reach
....

depth 21 in 27 minutes...knowing that...

depth 22 in 54 min
depth 23 in 108 min
depth 24 in 216 min
depth 25 in 432 min
depth 26 in 864 min
depth 27 in 1728 min
depth 28 in 3456 min
depth 29 in 6912 min

So basically shredder 8 would reach a ply of 29 in just under 5 days...
could ANY human EVER beat it EVER? without computer assistance?
