No they didn't.
Almost all the deaths and infections occurred AFTER the shutdowns and continued to rise for over a month, long past the 2 week incubation period.
Even Cuomo himself admitted just last week, that 66% of new infections came from people on lockdowns.
Your analysis accumulates infections for the entire 7 weeks since shutdown, and compares them to the 3 week accumulation while cases were rising until mitigation flattened the rise.
Apples vs oranges.
