			The '''Total Skill Index''' (or '''TSI''') is an official measure of a [[player]]'s abilities.

A player who is average in several [[skills]] (''e.g.'' inadequate in [[defending]], [[passing]], and [[scoring]], but with excellent [[stamina]]) will often have a higher TSI than a more specialized player (''e.g.'' excellent defending, but everything else poor or lower).

			As a general rule, the higher the TSI, the better the player. This is always true for a keeper, however, there are problems with this theory. A player who is average in several [[skills]] (''e.g.'' inadequate in [[defending]], [[passing]], and [[scoring]], but with excellent stamina) will often have a higher TSI than a more specialized player (''e.g.'' excellent defending, but everything else poor or lower). TSI also increases with [[training]] and it can also increase and decrease with [[form]]. Sometimes, TSI will drop even though form does not. This is an easy way of spotting that a background form change has occurred, and the form [[sub-level]] has decreased.

	~~TSI~~ for ~~[[goalkeeper]]s~~ is ~~a different matter. The higher TSI for a keeper~~, the ~~better~~. ~~Since a keeper only specializes in one skill,~~ [[~~goalkeeping~~]] ~~skill can be measured quite accurately based on their~~ TSI ~~and form (''e.g.'' using http://www.hottrick.org/hattrick_keeper_tool.php)~~.		== Formulas ==
			The formula used for the calculation is unknown, but several somewhat successful attempts have been made in approximating the true function. {{based on opinion}}It is rumoured that [[HT-Bjorn]] proclaimed he'll change the TSI calculation formula as soon as someone figures it out.

	Interestingly, ~~goalkeepers~~ typically have higher TSI at the same skill level than outfield players. A common theory is that both form and stamina have a multiplying effect on the TSI, whereas the other skills (for keepers, goaltending only) contribute as a sum of exponential functions.		=== Goalkeeper case ===
			Interestingly, [[goalkeeper]]s typically have higher TSI at the same skill level than outfield players. A common theory is that both form and stamina have a multiplying effect on the TSI, whereas the other skills (for keepers, goaltending only) contribute as a sum of exponential functions.

	[[~~Set Pieces~~]] and [[~~experience~~]] ~~do not affect the TSI~~.		TSI for goalkeepers is a different matter, since a keeper only specializes in one skill. [[Goalkeeping]] [[sub Level\|sub level]] can be measured quite accurately based on their TSI and form. For Goalkeepers an approximated formula for TSI calculation is:<blockquote>{{Hu/Formula\|\|formula=TSI<small>goalkeeper</small> = [ ( 0.025f + 0.1 ) * [ 10 ( s - 1 ) ] ^(3.4) ] / 100}}<small>
			with f = Form
			and s = Skill (1 = disastrous, 2 = wretched, etc.)</small></blockquote>

			=== Outfield players case ===
	== ~~TSI approximation~~ ==		For outfield players, the formula for TSI calculation should be as the following one:
	~~For Goalkeepers an approximated formula for TSI calculation is:~~		<blockquote>{{Hu/Formula\|\|formula=TSI = sqrt(f) * sqrt(st) * ( X * [ PM^3 + DE^3 + SC^3] + Y * WN^3 + Z * PS^3 ) ^2}}
			<small>
	~~TSI = [(0.025f+0.1)[10(s-1)]^(3.4)]/100~~		f = Form (1 = disastrous, 2 = wretched, etc.)<br>
			st = Stamina skill <br>
	~~With <tt>f</tt> = Form and <tt>s</tt> = Skill (1~~ = ~~disastrous, 2~~ = ~~wretched, etc.)~~		PM, DE, SC, WN, PS are the skills (Playmaking, Defending,Scoring, Wing, Passing skill)<br>
			X, Y, Z are fixed constants (unknown)</small></blockquote>

	For outfield players, the formula for TSI calculation ~~is of~~ the following ~~form~~:

	TSI = sqrt(f)sqrt(st)(A[pl^3+d^3+sc^3]+Bw^3+C*pa^3)^2

	~~With~~ <tt>f~~</tt>~~ = Form (1 = disastrous, 2 = wretched, etc.

	~~With~~ <tt>st~~</tt>~~ = Stamina skill

	~~With~~ <tt>~~pl</tt> =~~ Playmaking ~~skill~~

	~~With <tt>d</tt> =~~ Defending ~~skill~~

	~~With <tt>sc</tt> =~~ Scoring skill

	~~With <tt>w</tt> = Winger skill~~

	~~With~~ <tt>~~pa</tt> = Passing skill~~

	~~With A~~,B,~~C being~~ fixed constants (~~up to you to find them ;-)~~)
