Hi!

Since the intro of the 3-5-7 MM players are complaining about being bottom tier too often, or waiting long times for a new battle. IMO that's a direct consequence of non-appropriate "mixture" of tank tiers, because for 3-5-7 to work as we players expect (being top or mid or bottom tier in about equal number of battles), we'd need some kind of active tanks' tier pyramid:

 

tier-10        *** (3)

tier-9        ***** (5)

tier-8      ********* (7)

tier-7     *********** (9)

tier-6    ************* (11)

tier-5   *************** (13)

tier-4  ***************** (15)

 

This pyramid shows us that for a fair distribution of battle MM we'd need at any time 4 times as much tanks in tier-5 as in tier-10. IMO this isn't so, but I lack hard data to prove it. However it looks like that data can be obtained form WoT servers. Is there a good soul that would run a simple query through yesterday's battles, just counting tanks by their tiers, like:

Select tank_tier, count(*)

from ?

where battle_date = yesterday

group by tank_tier;

 

 

If this query would succeed, I fully expect to get an obvious explanation why we're not satisfied with the current 3-5-7 MM.

 

BR,  Iztok

Yes, that data can be obtained from WoT servers, but only WG has access to them...

Meanwhile, here's some data you can use.

http://www.vbaddict.net/statistics.php?tier=0&tanktype=0&nation=0&premium=0&modeid=0&team=0&battles=100&groupby=1&fieldname=battles&server=

Yes I know that vbaddict only has stats from battles played by players who use ADU (or whatever it's called), but you can see a pattern...

Thank you!

But I'm afraid data from vbaddict are"skewed" toward top-tiers - not many non-noob players (most vbaddict population) are seriously playing tiers 4-7. And those tiers directly affect the fairness of MM in high tiers.

Sorry, but why would you expect a 3-5-7 system to result in "being top or mid or bottom tier in about equal number"?

Because Math is hard.

At this point I'd settle for being top more than 2% of the time.

A pattern yes, but not one that is going to reflect the actual server population.
