There are a fair few updated speeds to be entered and they will all find their place in due time, I think it makes it a lot easier if you give your current name and position on the list if its an improvement on a current speed or confirm you are a new entry to the list mostly because from a list of a few dozen when it started its now getting to be a long list.
The obvious UK improvements are headed by yesterdays 270.965 mph in the standing mile by Guy Martin and the rest of the years speeds have been forwarded but can easily be sent again.
