I also avoid letting the reader make assumptions. HasPlayerJumpedRecently is bad. What does recently mean? HasPlayerJumpedInLastTenMs is better, even if it's a bit long...Which highlights that it should probably be refactored into a more flexible value; MsSincePlayerLastJumped.
If you arent assuming a time var wth Ms is milliseconds you aren't doing games dev so that one slides with me.
I use to be quite fond of short identifiers, especially ones the make the signs “line up”… until I worked with code long enough that I forgot what I did and had to read it again.
Which is an argument that this is not truly gouging - there's just a demand surge and a supply crunch and the market responds the same way as if it was a business conference in town.
Another thing worth pointing out is that the market of available Airbnbs clears out from the cheaper units first. So it may look like prices are shooting up, but really it's just that all the normal priced ones are gone.
It was an unconvincing argument then, and is an unconvincing argument now.
