It's not hard to see it ... this is what it looks like across my client work, using my Comp Segment framework (you know how to calculate Comp Segment performance, right?):
If "normal" is +3%, we'll set the axis at +5%. Then in March we see a +5% comp, followed by a nice comp in April and a bonkers comp in May. From there, comps slowly begin to reset closer to normal. For the April - September timeframe, the average comp is +27%. That's what a COVID-bump looks like. Normal performance (+3%) becomes +27%, and the bump has a natural peak and then cools off.
Of course, if the maskless Midwest continues to burn down, then there may be additional restrictions, and those restrictions might inspire another COVID-bump. So we don't know what is going to happen. We do know we can use our Comp Segment framework to measure what is happening, and act accordingly.
