I tend to view 1–10 ratings differently than 1–5. 1–5 is more like (American) letter grades where 3 stars equals a C and is average. On a 1–10 rating, it’s more like percentages so 9–10 is an A, 8–9 a B, 7–8 a C, 6–7 a D and less than 6 an F. I’ve seen elsewhere that at least one aggregator does similar to convert between 1–10 scales and 5-star scales so I think that this is a common unspoken assumption of the relation between the two scales.
