I have a broad question to ask:
What exactly are keyframes? And more specifically what impact do they have on the timelapse sequence?
Now, before you say "isn't it obvious?!", my understanding is that setting keyframes is a time saving device which allows you to adjust exposure of only a small number of frames across the whole sequence. Once these have been established and adjusted, the LRT goes to work and automatically adjusts the other non-keyframes so that the full sequence is smooth.
At least that's what I understand.
However...
I'm looking for a deeper understanding of how keyframes operate.
This is motivated by the sequence I'm currently putting together. It is set in a dark cave with light streaming in through an opening. Occasionally the clouds cut the sun's path leading to something which looks like a "cardiovascular work out" in the LRT preview window.

I'm currently weighing up how to process this and have been reading other threads which discuss similar issues.
The recommendation in these was simply to set one keyframe and "try to decrease the contrasts (shadows, highlights) on the whole sequence."
This feels a little lazy to me and will inevitably lead to mediocre output. The alternative would be to use no keyframe and manually adjust each frame. A lot of work but the result I imagine would be much better.
I'm not that happy with either of these choices as one leads to poor output and the other hours and hours of processing.
Hence why I'm looking for a deeper understanding of what keyframes do and how they effect the other frames around them.
With better knowledge, I'm hoping I might be able to place keyframes strategically and cut down my work load.
Many thanks.
