Im not sure if this has been covered in a thread yet (I searched, all i could find was offhand comments) so i apologize if this is old news.
I was bored, and i was wondering what the specific conversion is between in-game APM (The little box that appears when pressing M when watching a replay) and real APM (Your actions per minute), I thought they may have fixed that discrepancy by now (I'm fairly sure Dustin Browder mentioned working on a fix to it at some event day[9] and losingID8 went to)
Well, as the thread title suggests, they didn't. Using a metronome i clicked once per second, and watching the replay my APM was consistently 40.
So for those of you who enjoy the manhood measuring contest that is APM, just multiply your in game APM by 1.5.
As a side-note, this all started because I was worried that I was playing with similar APM than when i used to play brood war. I was a fairly lackluster Broodwar player, rocking a cool-headed 100-110 apm, But now it turns out my SC2 APM is actually 160-170 on long games, which i never expected to be able to reach. Also APM=/skill, it is merely loosely correlated with it.
EDIT: I realise that this has nothing to do with strategy, i just posted it in the wrong place.(im sleepy), surely a benevolent mod could help a brother out.

The APM meter on replays is actually measuring actions per game minute is why there is a discrepancy, (You're playing on fastest)
I kinda doubt they will fix this because they're maintaining consistency with all the measurements of time as game time, The unfortunate thing is that they didn't make fastest 1:1 game time to real time since it is the standard play speed.
|
Kind of ridiculous that this still hasnt been fixed. I'm kind of astonished that they haven't bothered to change this. Perhaps this also makes the income tab completely whacked. This means, instead of 160apm im probably sitting over 200 over 30 minute games (Which is what I should be at).

What I want to know is why is normal considered normal when everyone plays on fastest. The whole conversion between game time and real time can be confusing and Im just wondering why it exists, is it just a legacy artifact from BW, and if so why was it that way in BW

Moved to the main SC2 forum.

Yay for exactness. I tried calculating it myself but always ended up with a multiplier of around 1.33. Your method sounds a bit more precise so I'll just go with the 1.5 value. Also, I've had the same experience with moving from BW to SC2 in terms of my APM being a lot higher.

Are you sure it is 1.5? I have heard it is 1.4 exactly (the speed of the game on faster).

From the liquipedia article, "faster" is 38% faster than normal, which is how APM is calculated. So,
SC2 APM * 1.38 = SC:BW APM
So, someone with 150apm according to the counter in the game is really playing at 200 apm in actual minutes instead of "game minutes". Or, alternatively, the game isn't calculating apm, but rather action per "43 seconds")
On that note, why does blizzard count seconds on a speed no one plays at? It's true for build times too and everything, and it's confusing. It's not even a nice ratio you can do in your head.

I made some tests on the actual "time rate" conversions, you can find the full results in this thread : http://www.teamliquid.net/forum/viewmessage.php?topic_id=117215
TL;DR : the fastest speed setting is at least 36% faster than the reference speed (build time numbers) and it might even reach something like 40% considering that the normal speed setting is 3% slower than reference - I think a good average approximation would be 38%, that means if your APM displayed in the replay is 100, your actual APM was more around 135-140
I will probably redo the tests when I will get a new comp, as I feel that simply running the game in windowed mode in background induced some discrepency - hopefully that will disappear when I get a much better comp

A month or two ago Day9 said he brought up this issue to the developers, who were apparently not aware of it, and they promised that they'd fix it to be more accurate with real time. I haven't really looked at APM since then, but it's possible that the old experimental data is now outdated.

wow this means I have pretty decent apm lol

I doubt they have or will fix it in the near future. They have so many other more important things to worry about. But I still hope they do
|
Well the obvious solution is to change the term to AP43S
|
It shouldn't really matter because everyone has the same timing so the apm will still be the right differential.

Yea, propotionally you still suck compared to the Korean pro's..

How was the APM calculated in BW in comparison to the current APM calculation in SC2?
From what I understand, real APM in SC2 is slightly higher than the indicated amount, but how does it translate to BW APM calculations? (No, I am not trying to say SC2 APM is the same as BW APM gameplay wise , I am merely asking concerning the technical side of calculating the APM itself timewise)
|
I agree this is retarded and needs to be fixed.
|
so 20 x 1.38 = 27.6!!!! YAA!!! im the man.
|
I imagine it would be fixed before release but its not like you do not know that your apm is higher per real minute.
