I tried the above (modifying to 10) but didn't notice much difference.

I couldn't access the website at luxik.cdi.cz/~devik/qos/htb/. Is it 
documented
elsewhere?

Possibly may be the case.

As suggested in the 'Practical Guide to Linux Traffic Control' I also tried
setting HTB_HYSTERESIS to zero in sch_htb.c but again didn't notice much
difference.

Anyway, this is currently the least of my worries, see my new thread!
