To explain this, let's say you had an electric clock that gained 1 minute every 7 years.
You could use that clock your entire working life, no problem. And on a day to day basis, you would not even notice the inaccuracy. It would gain 1/40th of a second every day. Totally unimportant for the purpose of day to day information about the time.
But if you kept that clock plugged in for a couple of centuries it would be a half hour off.
Speed figures are accurate enough for current handicapping, and that tells us nothing about how accurate they will be over longer time periods.
