My interpretation of the revolutions is that they happen only when the government as such becomes weak and is unable to perform the constant suppression. They do not happen just because the conditions are bad.

Bad condition themselves are not enough, revolution requires people to think at least some of them can actually gain something.

That could be. I'm thinking of the Chu–Han Contention and the Warlord Era in China as times that it was probably the case - In both cases goverment control collapsed and there was not just one rebellion but a whole bunch that all sprang up at once and then proceeded to fight eachother! Arguably some of that happened during the Russian Revolution too.
