PLQ qualification_rate_bytes_per_second question

[LimeHat]

Should qualification_rate_bytes_per_second calculation take into the account all traffic that is sent during the qualification phase, or be recalculated independently for each min_sample_interval?

E.g. if the test duration is 30 seconds, sample_interval is 10 seconds, and the generator sends 300 bytes in the first interval, 400 in the second, and 200 in the third. Shall the generator report

• $\frac{300}{10}$, $\frac{300+400}{20}$, $\frac{300+400+200}{30}$, or
• $\frac{300}{10}$, $\frac{400}{10}$, $\frac{200}{10}$

Changes introduced in #126 seemingly hint on the latter approach, but want to confirm if this is indeed the expectation.
