Dota2 Meta Grid — Data skill for Claude Code

Dota 2 Meta Grid

**Climb MMR by picking the heroes that are actually winning this patch - shown right in your hero picker.**

Your MMR comes down to two numbers: **how many games you play** and **how far above 50% you win them**. This tool works on the second one. It takes live pub win rates, keeps the heroes that win the most in each role on the current patch, throws out the ones that lose at *your* rank, and installs the result as an in-game hero grid - best pick on the left.

The MMR math

**MMR gained = games x (2 x win rate - 1) x 25**

A ranked game is worth about 25 MMR either way. At 50% you stay where you are, forever. Every point above 50% is worth about half an MMR per game:

Your win rate	MMR per 100 games	Games to climb one medal (~770 MMR)	Games until you're 5-in-6 sure to be up*
50%	0	-	-
51%	+50	~1,540	~2,500
52%	+100	~770	~625
53%	+150	~510	~280
55%	+250	~310	~100

\* Luck swings your MMR by about 25 x sqrt(games). Your edge only outgrows that after roughly 1 / (2 x win rate - 1)^2 games.

Three things follow from this table:

1. Small edges are the whole game. Nobody holds 60% at their own rank. A steady 52-53% is what a climbing account looks like.
2. A hundred games prove very little. A genuine 52% player is still down after 100 games almost a third of the time. Don't drop a hero - or your mental - over one bad week.
3. There are only two levers: play more, and win slightly more often. The draft is the cheapest place to find "slightly more": it costs no mechanics, no warding guide, no coach.
