Blindability

What it is

A personal draft-analytics tool, focused on mid lane, that rebuilds Machine LoLing's "blindability" method from Riot match data. It separates three things that tier lists blur together: champion strength (win rate), matchup consistency (how much results depend on the enemy picks), and synergy consistency (how much they depend on allies). That helps decide which champions are safe to blind-pick and which only work as counterpicks.

How it uses the Riot API

• League-V4: samples ranked players from the ladders (Gold through Challenger) on EUW, NA and KR.
• Match-V5: recent Ranked Solo/Duo match IDs and match details; timelines for about 10% of matches (gold/CS/XP at 15 minutes).
• Champion-Mastery-V4: a limited sample of players, to estimate typical champion-pool size.
• Data Dragon: champion names and icons.

Output is aggregate only. Player identifiers are used to fetch match histories and stored hashed. The client follows Riot's rate-limit headers, honors Retry-After, and fetches each match once.
