Key Takeaways & Head-to-Head Analysis
The Ultimate Target:
Priessnitz 2.0 proved to be the easiest matchup for the challenger, with
Grail completely dominating the match scoring an impressive
80.50% (71 Wins, 10 Losses, 19 Draws).
Toughest Opponents:
Grail struggled to find its footing against the top tier of the gauntlet list.
Its lowest score was against
Arcanum 2.7 at
37.50%, closely followed by
Petrel 3.3.1 (
39.00%) and
Lambergar 1.3.0 (
39.50%).
The Break-Even Points:
The balance threshold for
Grail 2.0.0 sat perfectly around
BitBit 1.6.0 (
50.00% flat) and
Lozza 10.0 (
50.50%), showing exactly where its current strength holds parity.
Conclusion:
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.
The update is a massive success for raw strength enhancement, but optimization against top-tier defensive setups remains the clear goal for the next build.
Technical Review: Time Management Issues in Grail 2.0.0
Issue: Engine loses approximately
5% of its total games due to losing on time (Time Forfeits).
Status: The 2,500 games in the final report are
100% clean.
Any games that initially resulted in a time forfeit (~5% of the total pool) were re-run until a natural game conclusion (Win/Loss/Draw) was achieved.
