-Range is the distance it tries to keep (LG reaches 768). Lane is how far it may drift sideways before it turns back, so it does ADAD in front of you instead of circling (0 = no limit). With push in / back off off, it always holds its range.
+Range is the distance it tries to keep (LG reaches 768). Lane is roughly how far it may drift sideways before it turns back, so it does ADAD in front of you instead of circling (0 = no limit; while it's also closing in or backing off, the real drift can be up to ~30% more). With push in / back off off, it always holds its range.
 
 Underneath it's plain console settings, if you'd rather: `./rcon addbot lgbot <aim>`, `./rcon set lgbot_move <1-5>`, and `lgbot_strafe_min`, `lgbot_strafe_max`, `lgbot_fake`, `lgbot_range`, `lgbot_range_play`, `lgbot_speed`, `lgbot_lane`. The plugin rereads them every second. `set lgbot_debug 1` writes one line a second about its movement to `home/minqlx.log`.
 
-The bot fights the nearest human. Its own movement only takes over when you're within LG reach (900 units) on about the same floor; farther away, the normal bot AI walks it over to you. If a wall blocks its strafing for half a second, it lets the AI walk around for 1.5 s. One lgbot at a time.
+The bot fights the nearest human and sticks with them unless someone else is clearly closer. Its own movement takes over when you're within 900 units (a bit beyond LG reach) on about the same floor, and keeps going until you're past 1000. Farther away, the normal bot AI walks it over to you. If a wall blocks its strafing for half a second, it lets the AI walk around for 1.5 s, then longer (up to 6 s) if it keeps getting stuck. It speeds up and turns like a player (a full left-right reversal takes about 0.2 s), not instantly. One lgbot at a time.
