Does the client not reviewing and letting the gig end affect my rating?

[timaucoin]

I just had an order finish where the client didn't respond after I sent the work so it just sat there until it automatically closed. So they never wrote a review for the order. Now I just noticed my overall rating is 4.8 when it's been 4.9 for years. Does not reviewing/letting the order close affect my rating?  Ratings are everything on Fiverr.
