Six months ago, I was in the market for a treadmill. I shopped online. Found what I was looking for and I had it shipped with someone to assemble it and set it in my house. That assembly costed me US$125.
You might say, ‘Why have you not opted to assemble it yourself?’
Relative estimation. I have estimated that professional assembly people can probably assemble it between 1 to 2 hours. I can assemble it perhaps in 1 day or more. In fact, some assembly companies deliver the fully assembled treadmill and they will just carry it into your house and done setting it up in 10 minutes!
It’s not worth my time to assemble it.
Be cognizant that the effort to complete a certain story varies from one person to another; from one team to another. One’s easy stuff is very hard or almost impossible to others.
Everything is relative.
