Dear Hemant Kumar Patni,

I got data about MCNP speed from Health Phys. I may not find
the reference, but remember that organ time was about 1-2 hours and
all organs calculated two days or so. MCNP team published oficcial
report about lattice speed tallies with speed-up 100-200 times at 2004,
but used it for some medical applications since 1996 or so.

Sincerely
Alexander Vlasov

PS. Sorry, I wrote wrong dimensions in my previous post.
Must be AM 254x127x222, AF 299x137x348
