I pasted the image of the chart into ChatGPT-5 and prompted it with

>there seems to be a mistake in this chart ... can you find what it is?

Here is what it told me:

> Yes — the likely mistake is in the first set of bars (“Coding deception”). The pink bar for GPT-5 (with thinking) is labeled 50.0%, while the white bar for OpenAI o3 is labeled 47.4% — but visually, the white bar is drawn shorter than the pink bar, even though its percentage is slightly lower.

So they definitely should have had ChatGPT review their own slides.
