F and G — the same on both scales
| Rating | Certificates | Share of all certificates |

| F | 1,216 | 2.1% |
| G | 1,906 | 3.2% |
⚠️ The two scales are shown apart on purpose: adding a « B » from the 2026 scale to « B1+B2+B3 » from the 2009 scale would produce a number that exists nowhere. F and G belong to both, so they are counted in neither distribution and shown on their own. How the two scales compare.
