So basically this is going by what Lucas said and Ep1 dialogue. Anakin has a midi count of over 20K and according to Lucas his potential is 2x Palps. Wouldn't this mean Palps has a midi count of over 10K? Ik Legends has higher numbers but this is the highest canon material.

A feeling of fullness, of power, of dark and demon mastery -- of secret lusts, unrestrained passion, wild submission -- all these things were in Vader's heart as he neared his Emperor. These things and more."
Highest recorded was 20.000 since Yoda was the benchmark, I would think he had 20.000. Exceeding this means above 20.000. So 30.000 seems legit. Double of palps potential would mean 15.000 in Sid. Though those numbers don't mean as much as people want it to be, as Anakin was defeated by Obi-Wan who had less than Anakin or Yoda.
