Some Matchmaker Statistics for Coaches

A few coaches have been asking me questions about the behaviour of our matchmaker. This post is targeted toward coaches who are already coaching in the matchmaker. If you are interested in coaching in the matchmaker, learn more here.

Matchmaking Activity

Coaches in the matchmaker receive offers to coach students through Steam chat. The information below can help you understand when the matchmaker has historically sent out the most offers. If you are trying to get more offers to coach, you can use it to be online and available to coach at peak times.
  • Peak time of activity in a week is at 1 AM on Saturdays UTC (local time). 
  • Peak time of activity on any given day is at 11pm UTC (local time).
  • Weekends (Friday, Saturday, Sunday) represent over half of all matchmaker activity.
Graph shows a three hour rolling average for the number of coaching offers sent via the matchmaker throughout the week with all times in the UTC timezone. 

Successful Matchmaking

The matchmaker fails to match a student with a coach when the student waits ten minutes or cancels after five minutes. The times in red are the times in the week where we need more coaches online. Overall, the matchmaker fails to match coaches with students about 20% of the time.

Lesson Types

Students can optionally choose to focus their coaching on a specific role or hero. The information below gives an overview of the topics people have historically focused on.
  • Students choose roles more frequently than heroes: Mid (35%), Carry (13%), Support (9%), Offlane (4%)
  • Coaches have been matched for lessons focusing on 51 of the 112 heroes
  • Most popular heroes are Storm Spirit (3%), Invoker (3%),  Kunkka (2%), Bounty Hunter (1.5%), Shadow Fiend (1.5%)
  • The matchmaker fails to match students with a coach more frequently for certain heroes: Spectre (85% failure), Invoker (50% failure), Bounty Hunter (42% failure)

All statistics from August 1st, 2015 to February 1st, 2016.

Coaches who are streaming live!

Hundreds of coaches have created coaching profiles on and many of these have a Twitch channel. Today we are announcing a list of live streams belonging to coaches. The page monitors all of the coaches Twitch channels and updates every 5 minutes to show live streams.

If you are looking for a coach, you can use this to discover coaches, learn about their play style, or improve through educational streams.

If you are willing to coach, you can use this to drive traffic to your stream and appeal to players interested in coaching.

To appear in the list, create a coaching profile and specify your Twitch channel name. Remember to link to your coaching profile from your stream's channel description. As always, please let us know how you think we can improve this!

Announcing Arc Warden Support

Dota Coach now supports Arc Warden lessons and scans for coaches which are on the top 100 Arc Warden players in DotaBuff's hero rankings.

Valve released the Arc Warden hero in December. Apologies for the lag time to Arc Warden enthusiasts. Site development has been on hold after Pajama broke his hand late last year.
