Well, regardless of the price or the [ahem] place of manufacturer, the stated purpose, as well as the obvious purpose of the TPS is to allow the rider to monitor any changes in tire pressure in addition to drawing the rider's attention to the tire pressure should it fall below a predetermined level. It is not nor was it ever meant to be used in place of a tire pressure gauge. Further, if that were tried, it would take riding the bike to see what the pressure in each tire was followed by a long cool- down period, a pressure adjustment and then another test ride to again turn the sensors on. It is not only easier but also the only practical way to check tire pressure on this vehicle using a hand- held pressure gauge.
Now besides all of that, only Mary Jane Tinklepants would use a Post- It note to keep track of any pressure offset readings on a motorcycle; real men would just dig the offset number into the dash with a dull awl, someplace near or perhaps directly into the LCD screen. Hardley riders would tatoo the offset onto their knuckles....

An instrument like this is to give me info. I don't expect it to give me hundredths of PSI, but I expect it to be +/- 1 PSI accurate. It should be as accurate as needed to show something before there is appreciable change on the behavior of the bike.
These sensors are made in France and cost several hundreds of dollars to buy. I don't accept having to add a post-it to my dashboard
