Draconian Feedback Formula

So I discovered eBay penalises a seller for 12 months - In my case I had a 100% rating for years - If a buyer gives negative feedback the seller goes down 0.05% to 99.5%

Based on eBay's totally unfair policy,  It takes the seller 12 months to get back to 100% even if they have numerous positive feedback's and not even one negatives whatsoever during that 12 month penalty period.

There is NO incentive or fairness whatsoever to enable a seller to be able to slowly creep back up to a 100%  before the anniversary date of the negative feedback received
