Can we get a little more detail on the "midfield stamina effect" section? A citation for the figures? A little text to explain them? --Mr Wednesday 19:18, 25 July 2006 (UTC)

This percentage relates to the impact of stamina on the midfield rating for a player with the same form/experience/playmaking rating

OK, do you have a source for the figures? Ideally, it would be something that we can link to. --Mr Wednesday 18:09, 27 July 2006 (UTC)
No source but I am pretty sure of the efficiency
If you can not mention a source for the research, this kind of data could be removed as inaccurate. --Jhattara 08:05, 28 July 2006 (UTC)
Accuracy is not measured by the knowledge of the source but by the formula efficiency. Remove it if you want, now we would then hide interesting information. You should then also remove information added in the TSI calculation and Form articles
I'm just saying that this kind of information should have some kind of research backing it up. --Jhattara 06:50, 31 July 2006 (UTC)
