When I looked into the account data of SBB, I saw that we’re nearing 500k actions. Looking at the 3 websites in that account, it really looks like a mistake to me 
When I do the calculation, I even don’t come close to 200k.
Hi. You should also see a table with details below.
How are you doing your calculation?
Update: I checked your account and indeed something is wrong with the totals. It’s not a big difference since you have many custom events, but still. We’ll take a closer look at this early next week.
I double-checked and it looks fine. You can consider disabling or limiting the built-in page scroll custom events.
