@elliottbnewcombjr I am no where near a perfectionist, but I do take my leads from those in the know and adopt what makes a lot of sense.
My first sent in Donor Model nearly 8 years ago was described as filthy by the Technician, I had no idea of what was meant by that until a later date and a curiosity got to me.
I do Photography and occasionally produce images that would be referred to as Macro, but not conventional, as I do the reverse lens technique.
I set up another Cart' to be Macro Recorded, that was a Cart' bought in to be a donor model, to undergo a rebuild, this Cart' was claimed to have approx' 300ish hours of usage.
The images focus point was the point where the Armature could be seen inside the Housing.
The images were quite something, almost extraterrestrial, the Crud and range of Colour in the particulate, was akin to viewing a terrain not seen on Earth.
The Cantilever also had Particulate attached that was almost the same thickness.
To make it easier to understand the inners were caked in filth of what origin who knows, the Cantilever was certainly carrying plenty of Hitchhiker Particulate.
Combine such a visual experience, with description offered through publicly showing photo records of a Cart' received by a Third Party Refurbishment Service.
It does not take much sleuthing to make a plan for ensuring a Cart' is in a much improved condition as it approaches the Mid to Later hours of recommended Cart' Life.
Cart' costs £XXXs - £XXXXs.
Cart' is functioning fine for a period and then the environmental impact has taken ahold.
Does one let the last 400 - 600 hours of usage, be substantially compromised, or does an additional cost be incurred to thoroughly clean and have the Cart' condition checked?
A conjecture can be, that a filthy Cart' with a £xxxx's price tag might not be much better at producing an end sound, than a Clean Cart' costing substantially less.
Any unwanted reports from a Service if about a bought as new Cart', will most likely be as a result of the way one is using the Cart'.
Surely a knowledge being made known of something being present, is a detriment or a set up for the cart', is being a detriment. Is well worth receiving, even if there is a cost to acquire the Valuable knowledge.
A Cart' condition is not life or death, whereas my home Boiler receives an annual check. As well my Homes Chimney and the owned Vehicle's. A friend electrician gives the owned homes electrics a once over every 3-5 years apart, when I was letting property the same checks were annual on let property.
Having items checked out that play a very important role is not unusual, skimping and avoiding such practices, now that is each to their own.
More important, I can't find anything in my suggestion on Cart' maintenance as being askew or incorrect, when the idea of keeping it as a optimised part is the consideration.
