FilterRatio Drop 0.00146 from 0.0019

Hi Guys,

i have a problem. My FilterRatio is dropping the more Plots in add.
In the beginning first few hundred plots i had a typical 0.002 to 0.0019 but since coming close to 900plots its degrading from day to day to now 0.00146 :frowning:

Is this normal? If not, what could be the reason? Anybody else experiencing this phenomenon?

I searched already this forum and googled without any success.

Thanks for your help.

Guys, nobody any idea? How are your filter ratios for 1000plots or more?
