Skyrocketed above 5% is an expression I would discourage anyone from using because it's a broken metaphor. Unless the trajectory of that rocket was a few degrees from horizontal.
How about grasshopper-ed above 5%?
Let's revisit that topic if the FED raises interest to 5%.
The number doubled in the last year. April 2025 it was around 2.3%, and has been jumping around 2-3% for several years. Skyrocking seems justified when looking at a greater picture.
Though, it's a longer process, not something that suddenly happened immediately. The combination of Steamdeck, proton, good gaming-distributions and Windows 10 phasing out, while Windows 11 sucks and becoming an AI+Ads-infested mess, seems to have pushed this trend. So let's see how high this sky will be.
