More like 99% +/- 1% TBF as an example. Although 100.2% +/- 2% would be another example.For e.g 98.10% vs 98%+.
Jano uses this "floor +" notation to avoid confusing some folks on the measurement plus / minus confidence interval. Or having to explain a perfectly reasonable measurement of 100.3% purity.
HPLC measurement error on raws is usually quoted as +/- 2% but I imagine on some raws it is tighter than that.
