They should be OK as long as you are sure about your overheads.

I use something similar and use ceil 286kbit while synced at 288kbit 
without problems.

If your modem is connected by eth rather than ppp then htb/whatever will 
see the packet size as ip len + 14 - so you need to account for that.

I think that produces a corner case (overhead < 14) where you would need 
to put in a negative number - I don't think that will work, but haven't 
tried.

Andy.
