If I understand you correctly, if your tire pressure drops from 50 psi cold to 44 psi hot then this is considered normal, less than a 12.5 percent decrease.
It seems to me that the range is a little high to truly be helpful.
Now if it would detect the normal increase in pressure as the tire gets hot and establish this higher pressure as the baseline then a decrease of 12.5 percent might be worth knowing about.
But I look forward to subsequent reports.
