Grail 2.0.0 has demonstrated a massive, clear generational leap forward with a +137 Elo gain over version 1.1.
While it systematically dismantled lower and mid-tier engines (scoring 60%+ consistently from Lunar 0.4.0 downwards), the gauntlet exposes a distinct ceiling when facing sub-2300 baselines like Arcanum and Petrel.
petrel scales badly at longer time controls, so it generally overperforms at ultrabullet.

Hi, and congratulations on Petrel’s progress!

I’ve only tested Petrel in ultra-bullet conditions so far, and in my 2026 WCETC tests it has actually performed very well.
