When there is perfect poop as well as some sticky poop, its generally known as isc, intermittent soft cecotropes. It means there’s some sort of microbial imbalance in the cecum. It’s not alarming, if it persists, the first thing to do is to try and tweak the diet, as a rule towards more hay and less pellets.

Is she eating a good amount of hay?

Round and smelly, yet still being the same general size as normal poops makes me think territorial poops (especially if there appears to be a sheen to them). My Fable has territorial poops very often, likely in reaction to be housed separately with another rabbit, therefore facilitating the urge to leave those more potent smelling poos, though how much of it is by her own volition, I don’t know (as I have never had her without the other rabbit).

As @Bam mentions, if it’s not happening often, I wouldn’t be too concerned considering they are of good size still and not overly mushed/malformed.

Yes, linked poop mans there’s some sort of gut slowdown. It is often related to shedding. A gut slowdown can cause gas build-up. It’s not uncommon that a splotch or sticky lump is the first poop a bun has after a bout off gas/gut slowdown.

Yes, it is normal. Daytime is “lounging-time” for rabbits and their GI tracts. Rabbits are crepuscular, meaning they’re mostly active in the mornings and evenings. With activity, you get  poop. This is more marked in adult rabbits and less marked in youngsters. It’s how it’s supposed to be.

If she’s eating and pooping normally, I’d say its normal, but it’s very good that you’re keeping a close eye.

An early sign of stasis is decreased appetite. This can be difficult to notice, because we always feed our buns a lot more hay than they’ll eat. It should be visible in the poop though, if a bun eats too little, the poop will get smaller and darker (aka peppercorn poop). This can happen overnight though, so its good to be vigilant.
