Visits Data is not matching when compared in Analytics for AEP Web SDK vs Client Side implementation

[test976]

We recently implemented AEP Web SDK for our website, following all the necessary steps. However we've noticed a discrepancy in the "Visit" metric when comparing the analytics between AEP Web SDK and Client-side implementation. The difference is approximately 20%. It's important to mention that all other metrics are functioning correctly, with a discrepancy of less than 3-5% for other metrics.

How are you performing your comparison?

Also, do hit-level metrics (e.g. Page Views) show the same discrepancy?
