Has anybody tracked whether it costs less to upgrade a unit all at once, as opposed to in steps?

In other words, is it cheaper to upgrade a catapult to an artillery, than it is to upgrade it first to a cannon and then an artillery?

If there is a difference, is it significant?
 
In Vanilla it's cheaper to upgrade a catapult to an artillery, than it is to upgrade it first to a cannon and then an artillery.
 
it is cheaper to do a multi-stage upgrade all in one go.

The cost is (Difference in Hammer cost)*3 + 25

The hammer cost portion will end up the same either way, but the +25 gets paid for each upgrade step.

So, in your example, going through the cannon intermediate step costs 25 more than going straight to artillery. Of course, it is likely that you would be doing the cannon upgrade well before the artillery upgrade so they 25 extra does allow you to use the units as cannons instead of as catapults while you wait for artillery to become available.
