[ADVICE] Success score tanking

Ive been doing very well on Fiverr since the day I made my account. I do about 500 orders a year at about 250$ average each. My success score was 9 for a very long time and being considered for Top rank (let’s be honest they don’t offer this rank in my category so that’s all lies). Suddenly in the last two months my SS has been tanking on all my gigs that receive orders. I have one that people rarely need as it costs them ~$50k in materials so it’s a luxury…well that score is still at 9…. But everything else is falling to 6 and now even 5. On the SS5 gig I have 0 competition and I mean it..I’m the only person offering this so I shouldn’t be compared to anyone. It’s a government form so there’s no way to fk it up..it’s just entering the customers address and adding a little more set info provided by the client so there’s no such thing as the client not being happy as there’s no way to add any different data. Like why is the SS tanking?? I spoke with support and they said Wow you have a mind blowing amount of orders so it’s only natural with this amount your SS to fluctuate more…There’s literally no way to do this project wrong or have an unhappy client and my delivery is 1day as it’s like 5 lines of text lol. Thankfully I’ve moved big part of my business to my website but still who doesn’t want 500 orders extra. I describe everything that’s included in the gig when I’m sending an offer like time, services, revisions and so on, I thank the client the sec they place an order and tell them if they need to provide more info on the requirements page, I update them in the middle of the project, I deliver with great instructions not only what the delivery is but next steps where to take the documents to make their process easier…. How is this not great communication. I always deliver days earlier. Only 5* reviews…60% repeat buyers with a 98 Repeat buyer score…What am I doing wrong? I have no score in red. Delivery in green is Strong positive and in grey I have Effective communication and client satisfaction (room for growth). It’s like they’ve changed the system and every new review is scored in a different way. I have a new order for that luxury gig and I’m sure no matter how I do my score will tank once I deliver.
