On one hand, I think some data is better than no data, so I think its fair to say that there is a lack of evidence for it being better in terms of in-game performance after setup based on it and that should just be the null assumption anyways.
On the other hand, its been over a decade since its been pretty well known that average FPS is not necessarily reflective of overall performance and throwing the frametime data into a spreadsheet and doing =percentile([range],.99) and =percentile([range],.999) and then dragging it to neighboring cells seems like a pretty minimal extra work for a commercialized channel. For niche testing like this, I’m less bothered by it because having some results seems better than nothing, but its still nice to see it pointed out.
Most phone calculators lack things like graphs, statistical tests, etc. Really just for people who are quired to use Ti calculators or learned to use them in the past. Better apps imo exist (like numworks graphing calculator) if you don’t have platform loyalty
