It should be true and according to the documentation[1], it also say same thing. But there's no correlation between hashrate and stress testing since all you need to do are generate and broadcast lots of transaction.
Stress-testing is very wide term
I see now a lot of transactions and too big (in my opinion) hashrate.
I haven't analyzed yet the blocks and transactions themselves.
You're right, but if you ask people about cryptocurrency stress testing, majority would say high/increased amount of transaction. Not about unstable hashrate or other unusual test.
Can't say you will find out interesting result from your upcoming analyze besides raising TPS/hashrate.
