@Séverine-and-Niels0 apologies for the late response. I believe that reviews from any guests who stayed during the evaluation period will count regardless of if you leave a review for them or not (although I'm still not 100% sure). They have 14 days as usual to complete their review, which is why the assessment period goes on for 14 days after the quarter being evaluated.
I don't know about the 11 day period @Robin4 mentioned, but he is more experienced than me, so would know best about this stuff.
A couple of things I'm still confused about though.
Firstly, if guests leave reviews during the 14 days after the period being evaluated but they did NOT actually stay during that period, i.e. they were guests just after, will their reviews be counted in the current assessment, or only counted in the next one?
Secondly, I don't really understand how my ratings tally up. In my stats, it says 80% five star reviews, but in my standards tab, only 78%.
It says "Your current progress towards the upcoming assessment is based on the following date range: 1 October 2016 - 30 September 2017 (Current)"
Why is this? I thought the assessment was based on ratings in the past year, so that date range would be 1 July 2016 - 30 June 2017. Why would it only take into account the past nine months?
