Here's a new term to keep you confused: AVERAGE

sheesh!

Thank you.

Here's one for you, as well. NAVIGATION

There is no navigational use for determining the average hourly change
in knots during a previous period of time. It cannot be used to
forecast future changes, will almost certainly be non-linear, and could
lead to some wildly erroneous conclusions about position.

It is common to project present speed, particularly for short
intervals, to predict future position. How fast you were running
yesterday, or even several hours ago becomes meaningless. The average
rate of hourly change in knots made would be useful for evaluating tits
on a boar.
