My personal observations makes me feel that it is 'badly' used to judge an account, because it really depends on what's going on in the RL of someone.

Very true! That's one of the reasons I created this dashboard. It's not made to judge people based one metric. By showing a lot of metrics at once, you get a much better view.
If someone withdraws some funds for whatever reason, but does interact a lot, they add value in another way.

On the other hand I do see a lot of extractions and also the hivedaily posts show every week there is more extracted than deposited. That's not sustainable in the long run. I think the people withdrawing also should look at that. If too many people keep withdrawing everything most of their earnings and hardly stake, the price will keep going down and there will not be much value to extract anymore for anyone.

For now I'll keep the KE values this way since I do want to get a warning when someone withdraws twice of what they earned.

Could it may be possible i can set these by myself in your tool?!

That's one of the thoughts I originally had. But now I'm developing it myself (and I'm no developer at all) I see that might be a difficult one. But I do want to try implementing that later on.
