I do not know how you can conclude this.
By that logic some odd 3/4 of the members of this forum don't look after their machines. More of us are messy and disorganized, than are tidy and organized.
Quite often we see photos of messy shops and spotless shops and lots in between. It would be interesting to know where the average is. You can make up to three choices. You can see results before you vote. You can change your vote! Of course the survey could have been better! But there is no...

I think it's better to look for oil on the ways and signs of oil running out of bearings and bushings. I want to see that oil. I can't do that if everything is always looking spotless or painted or clean.
I'd even go as far as to say that fresh paint and a spotless machine are a red flag for me. They make me wonder what they are hiding?
To be clear, I am not knocking those who like a tidy organized shop. I think that's their nature and its ok. But I don't knock a disorganized messy shop either. They are both just normal segments of the population. Neither one is a good proxy for a machines condition one way or the other.
