This is sort of inevitable though: if the disease were not serious and measures were an overreaction, you would see little change as they were lifted. If the disease were serious, measures were effective and they were lifted sufficiently late, you would also hope to not see much difference after they were lifted. The only cases one would expect to see a large increase in cases would be if the measures were ineffective (but then you’d also have seen an increase while the measures were in place) or if the measures were lifted too early.

Personally I’m mostly indifferent to whether or not the current restrictions are an overreaction, though I’m in the fortunate position of not being particularly severely affected by them. I would rather an overreaction than an underreaction.
