Difference in total score from reports and dashboards

[AlexanderChapurin]

Hello!
I run my lighthouseCI tests daily and usually I just check changes in total score. But today I was inspecting reports from last two weeks and found out that some runs have score that differs from the one on the dashboards. The difference is not that big, but still kinda confusing.

Here is a screenshot from my dashboard where I see a total score of 55

But the report has 52

Any ideas why is it happening?
