There are some books that support that point of view, mainly by G.P. Blair. He is
responsible for the bulk of 2-stroke exhaust system research. But his books are
geared towards design of a product to be manufactured, and not peak performance.
(except for one paragraph)

When repairing an engine that has failed, and was caused by detonation, and is often
followed by pre-igntion, I identify rpm ranges that may be running lean, and I decrease
the squish clearance to prevent the problem from reoccurring.
