What is the wingspan of the aircraft?

The wingspan shouldn't matter.

Altimeters make this less likely than you might believe. Perhaps you are the
one that doesn't realize something. As you admit below, you didn't put much
thought into your determination.

To convince me, I need an explanation of why wakes descend universally except
by some magic exception when someone is doing a 360-degree turn.

Perhaps you are not considering all the causes of turbulence that follow
an aircraft (in it's wake)?
