>who cares about a technique for tracking total number of any items sold?

Pre-digital calculator salesmen? Time is money and being able to do a quick mental math can be helpful before doing a more detailed inventory

>you could then just divide by the price, you don't need to coerce the total into being a tally mod 100.

That's why they gave more than one reason. Why laser focus on criticizing a single one?

For what purpose? Say you're a salesman of 7 different products/SKUs; you sold 186 products today. What do you do with that information?

You're still hyper fixating on one single point. And I'm not a businessman. I imagine businesses never do one thing for one reason like software functions.

Bankers can tell a lot from a security standpoint based on seemingly frivolous data. Maybe it's the same logic here. If you end every day swelling exactly XX0 products, something is amiss. It at least prompts a deeper investigation, since running through weeks of receipt/data takes more time pre-computer.

I'm 'hyper fixating' on the point that seemed nonsense to me, that I commented on, and that you replied to.

?? It lets me know how effective a product I'm offering is being sold? What do you mean?

I guess you can think of it as a "checksum". If your inventory count doesn't match the sales sum, something is wrong
