started writing reviews again after a while...noticing it takes 3 to 4 days now to get approvals. I am guessing they have a small staff to review them. Used to be within 48 hours.

No kidding.

I have noticed the slowdown as well

Yes, they must have staffing issues.  
A while back, I wrote a nice long review, but someone nitpicked that I wasn't "clear" on whether or not she did enough to warrant a 9 vs an 8.  

Really?

There are some reviews that are literally 2 sentences long and get posted.   Huh!

Remember the mods are quickly scanning these reviews to get through them all. From their POV, the onus is on you to clearly describe the sex in a way that justifies the performance rating you assigned to the provider. Sometimes when it gets too wordy, it makes it hard for the admins  to figure out what you’re talking about.

Perhaps a new review template would be in order then.

 
Details could have an Executive Summary/Abstract section at the start and then all the "story" narative following. From TER's perspective the scoring is really activity driven so as long as the additional activities that justify the above 7 rating they should be fine on the score.

 
Then all they need to do is look at the tone of the review to make sure it is largely objective and not some degrading/abusive tone. (I'm fine with the type of asymmetry here that allows overly positive tone to the review as everyone should be able to see that for was it is and it's not going to hurt anyone emotionally who was the object of the review).
