The meaning of "is within a percentage range"

Dear Teachers:

(1) Could you please let me know the meaning of the following sentences? In particular - the meaning of "is within a percentage range"

• Loss on Drying<731>: Dry a sample at 105° for 3 h: it loses NMT 7.0% of its weight, or some other lower percentage, or is within a percentage range, as specified in the labeling.

* Sources: https://www.drugfuture.com/Pharmacopoeia/usp35/PDF/1746-1747%20Microcrystalline%20Cellulose.pdf"

(2) My understanding: If you dry a sample, the sample will lose 7.0% or lower % of its weight by a percentage point like by 7.0%, 6.0%, 5.0%, 4.0%, 3.0%, 2.0%, or 1,0%. => Is this correct?

(3) It would be appreciated how the syntax of "Dry a sample at 105° for 3 h: it loses NMT 7.0% of its weight, or some other lower percentage, or is within a percentage range, as specified in the labeling." is.

- Dry a sample at 105° for 3 h:

- it (the sample) loses NMT 7.0% of its weight, or some other lower percentage,

or (the sample) is within a percentage range,

Is this correct?

Look forward to your help indeed.

Thanks and best regards,
