Apple Watch 8 takes hours to charge 50%-100%

My wife and I both have had our watch series 8 for about a month. Mine is a 45, hers a 41.

Every day when we go to recharge our watches the charge ring is at about the 4 o'clock position (charge remaining) if that makes sense. I will recharge my -45 in 40 minutes give or take. My wife's -41 at that same charge remaining point will take 3 plus hours to fully charge.

Does this seem correct or is there an issue with hers?

Thanks!!

See the 'How Optimized Battery Charging works' section in:

About Optimized Battery Charging on your Apple Watch - Apple Support

"When the feature is turned on, your watch delays charging past 80% in certain situations. In these situations, the watch's battery level remains between 75% and 80%. Your watch uses on-device machine learning to learn your daily charging routine so that Optimized Battery Charging activates only when your watch predicts it will be connected to a charger for an extended period of time. The algorithm aims to ensure that your Apple Watch is still fully charged when you remove it from the charger."

That might explain the difference. But see the rest of that section also.
