Blert Lost Ticks od Crecket

Blert Lost Ticks is an unofficial, community-made extension for blert.io.

A "lost tick" is a tick a player was off cooldown and did not attack. The extension computes them from the data blert.io already serves your browser and displays the results inline on:

• ToB boss room pages — total and per-player lost ticks
• Raid overview pages — a room-by-room, player-by-player matrix
• Session pages — totals across every raid in the session, with per-raid averages

Run-ins and boss transitions are excluded, matching Blert's own idle-tick logic. Sotetseg mazes are charged to every player equally, and a death is charged through to the party's last attack.

On a player's personal-bests page, each PB is badged with where that time sits in Blert's public distribution, e.g. "Top 3.2%". Scale 3+ times are scored against both the standard and the 1d Bloat (speedrun-tier) distributions, since Blert does not record which tier a given raid was — both badges are shown and you read the one that matches your raid.

One caveat worth knowing: Blert's distributions come from a view truncated at the 90th percentile covering only the last six months. Every badge therefore means "top X% of the fastest 90% of recent runs", and anything slower than that cutoff pins to exactly Top 100.0%. Blert's own split calculator carries the identical bias.

The extension requests no permissions, has no background worker, executes no remote code, and contacts no server other than blert.io itself.
