Success Score is inexplicable

[albertobellio]

Success Score has no apparent meaning.

It is high (8 or 9) in my least requested gigs.

It is low (4 or 5) in my most requested gigs, in areas that makes no sense. For instance, Order cancellations have a "Strong Negative Impact" in a gig where order cancellation ratio is 0%. Client satisfaction has a "Strong Negative Impact" in a gig with only 5-stars reviews.

"Effective comunication" has a Negative impact, but my client always rate me for my good communication, I always help them figuring out their needs and I'm very clear on the specifications of each single order.

Even if these evaluations by Fiverr were true, there's no way to tell what is wrong, leave alone how to fix it.

Is anyone in the same spot? Otherwise, has anyone found a key to improve his/her success score and is willing to share his/her observations on this new system?
