The code in routers.cgi currently does not know about the tera- prefix. It only does k, M and G. So, 1Tbit is displayed as 1024Gbit. The next version should support this, I guess... I just never expected such large numbers
If you wish to disable the totals, you can do this selectively:
routers.cgi*Options[targetname]: nototal
and you can also disable the 95th percentile with the option 'nopercentile'. I can't automatically disable totals on all guage counters, since some may want this (eg, where the counter gives a rate). Maybe the default should be changed and then add a new 'total' option? I'm a bit wary of changing the default behaviour now though, since it causes unexpected behaviour changes when people upgrade.
