I have not learned the method doing animations through KeyFrames (yet), but it
seems to be the way a lot of people do things.

You certainly are a ... polymath. :D

Noted. Thanks!

Well, sure.
I also have learned not to use the clock variable directly, as I have often run
into the situation where I want to modify something halfway in.
So rather than having to hunt down all of the instances of clock, I usually
start off with
#declare Clock = clock;
And then all I have to do is edit my single function.
#declare Clock = clock*2;
#declare Clock = clock*360;
#declare Clock = (clock*9)+1;

Fascinating .... and sometimes dismaying, when you've totally miscalculated
something in a long train of ... maths.
