I have a question: The total amount work to verify N 1MB blocks is about the same as single N-MB block, right? For example, 32 1MB blocks take about the same amount of work to verify as a single 32MB block, right?

No. The scaling of validation time is quadratic (look up quadratic growth if unsure what this means). In other words, 32 1 MB blocks != a single 32 MB block. Segwit aims to scale down the validation time and make it linear. Classic (BIP109) adds a sigops limitation to prevent this from happening (so not a solution, but limitation to size of TX IIRC). If anyone claims that this is false or whatever, that means they are saying that all the people who signed the Core roadmap are wrong/lying (2 MB block size limit is mentioned there IIRC).

It can be set to 1.1MB easily, right?

That would work.

Thank you Lauda: https://en.wikipedia.org/wiki/Quadratic_growth ... ouchie; so if a 1MB block with y transactions in it takes x seconds to validate then 32 similar 1MB blocks will take about 32x seconds but a 32MB block can be expected to take about (32y)²x seconds. Or is the quadratic growth on something other than transaction count?
