Hmm. So it's been almost 24 hrs since the last coat. Am I going to
regret it if I add another coat 24-48 hrs after the last coat?

One thing to watch for is making too many layers with a semigloss
finish. Each layer reduces the clarity and begins to hide the wood.
Usually you do all the base coats with "clear" and then do the final
satin coat with the satin or SG finish.
I've only used the minwax stuff and have applied extra coats within
minutes and sometimes weeks later. I would avoid any recoats in the 4-24
hour range since the surface is too dry for the next coat to adhere well
and too soft to properly "scuff" it up.
After 24 hours you can do whatever leveling sanding you need and apply
another coat.
