For every 10 seconds in real life,30 seconds pass on the game clock(meaning it'll take about 6.67 mins to complete a period set to 10 minutes if the clock never stopped). The number SHOULD be 20 seconds.
On those same settings,with penalty time scale in the middle,the clock does go according to the period length(so if you have 10 min periods,the 2 min penalty will take 1 minute in real life,as it should).
Calculated stuff taking into consideration that final 10 seconds of 1st/2nd period both actually take 10 seconds and final minute of 3rd is actually a minute. Then just used the 10 second real time sample I did before to calculate the other 19 minutes & 50 seconds of the gameclock(in 3rd periods case,just 19 minutes)
5 min period are actually 3.8 minutes(3rd period being 4.5 minutes)
10 min periods are actually 6.8 minutes(3rd being 7.3 minutes)
15 min periods are actually 10.1 minutes(3rd being 10.5 minutes)
20 min periods are actually 14.3 minutes(3rd being 14.6 minutes)
So by this logic, if you want actual 10 min periods,the period length should be set to 14-15 minutes and the penalty time scale should be set between 1-2. I tested this out,and it does give the results that 10 min periods with penalty time scale in the middle SHOULD be giving us. So for all those slider makers using 10 min periods, maybe this is something that needs to be considered when looking at stats like shots on goals,goals and penalties. 10 min periods don't actually mean 10 min periods,so maybe some stats which might be lower than they should be,are lower for good reason,cause the period lengths aren't actually as long as we think.
Feel free to test out things like this for yourself and provide feedback as well. Want to see if other people are getting same type of results as I am in terms of the game clock time compared to real life time.
