What do you think explains redshift variability best?

Please explain how redshift variability can be explained by lightspeed decay. Note that in my example I am referring specifically to creationist claims that lightspeed has been slowing down in such a way to make current astronomical observations consistent with a universe no more than 10,000 years of age.

The only people I've come across who've written about redshift variability are in the YEC camp.

I admit I haven't looked for info in other sources. Jargon laden explanations = a heavy slog, a slog I'll take if the source is recommened. Any theories, theorists you favor?
