I did hear that 900KIAS was also authorised at one point and I do know some that got to that with ease before the DECUs were trimmed back following some uncontained engine issues.
We still do OECs these days and you can read about their policy here:

Thanks for the correction - I was going from memory. The 800 KCAS was what I remember from the R to S trials and I thought that had become the NE limit - my mistake. Must dig out some old Manuals ....
