How does offering "free for the month" impact asset sales afterward?

I have a plugin asset on the Marketplace and I’m curious about how its sales will be impacted after being featured in the “Free for the month” list?

I had a plugin featured as free for the month in 2020. In my personal experience, after being featured, the plugin continues to sale more or less the same than before, maybe even a little more. What helps a lot is that during the free for the month time, the plugin gets a lot of reviews.
