There won't be, 50% is way too far off, I think (from experiments I did 30 years back) that about 12% is the limit, when I had access to the best regenerators. Regens don't even get used anymore. I forget the actual limit I probed, but I know 1/2 over is way too far to go. > > -Warren Block * Rapid City, South Dakota USA > _______________________________________________ > freebsd-chat@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-chat > To unsubscribe, send any mail to "freebsd-chat-unsubscribe@freebsd.org" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkh6MrsACgkQz62J6PPcoOmBrwCfRIbcU4yoZrApBR32AYdFBqtn t6wAn1yw4mK9WE0jxjEu7/XTI1iG/y3N =mZOo -----END PGP SIGNATURE-----
