"Unreasonably large" is only your opinion not a fact.

"Ridiculous" is also only your opinion not a fact.

Most Fritz users are not ignorant about the program.  The ones that are probably
will not mind that it is performing at about  95% instead of 100%.

I only mention this to indicate that even 256 meg may not keep Fritz from
hitting 100%.  I never said it would not "play well" when it does hit 100%.
As far as I can tell it can hit 100% and still search pretty effectively for a
few more ply.
