Well, for RT the score will not change at all between Episode 1 and Episode 8 as the score posted on the site for TV shows is solely based upon the first set of episodes critics are given to watch for a season (be it just a pilot, or like with Netflix, typically up to 4-6 episodes, sometimes the whole season in the case of 1/2 hours).
So if RT has a 75% for DISCO after the pilot, it will stay that way as they do not then further aggregate later reviews, mostly because only a few publications review shows week on week, whilst most will post a review based on pre-release screeners sent out. It's the same with Metacritic also. Only if a reviewer changes their mind with a new review and either RT picks it up, or the reviewer requests his/her original review be amended, will scores fluctuate down the line.
IMDb will be different as it based on users continuously adding their
own scores to the aggregate, but I would presume that the vast majority of people will, again, score it based on the pilot, rather than the 8th episode - but, there is the option to change your score, so perhaps the more devoted IMDb user will reflect on their original score as the show develops. IMDB also purports that they use a "Weighted Average" aimed at mitigating those attempts to simply change a film/show's score - see
Ghostbusters 2016, which has 27519 recorded 1-star scores (17.6% of all reviews cast), and by the general internet's account of early "spam reviewing" of the film, it should be closer to a 2 or 3, rather than the very average 5.4 where it currently sits.
In the end, both RT and IMDb are very flawed models, and as
@Serveaux rightly pointed out, DISCO sits at a healthy 88% "Want To See It" and on IMDb the show's page has moved up 30 places this week to become the 90th most viewed page on the site. So, interest is out there.
What will be interesting is if
anyone releases any worthwhile viewership ratings for the show. Following DISCO's pilot airing on CBS (viewership of which can be tracked in the old fashioned way), it moves to two online/streaming platforms, which have been notoriously difficult to get either real-time or aggregated viewing figures for. Netflix regularly refuses to release how many people watch a show and they have deliberately changed their star/% system to reflect how much a show reflects the remainder of your viewing patterns, rather than how much you and other people actually liked it.

little more interested as the air-date creeps up
