well try that:

Reuse encoding use complete research from first pass and refine Rate Control at really high speed (like fastest preset speed but with veryslow preset quality). And reuse mode will refine and refine and refine again Rate Control in Npass mode certainely with better quality than classic 2 pass RC mode, and with better constrained Rate Control at each pass.
IMO with this particular mode encoding, --strict-cbr will be even useless if you use many pass and you can expect better quality too.
