TSI – the peekhole into a players soul

TSI or Total Skill Index is what hattick use to summerize how good a player is in total. The exact formula is a ‘secret’, but many attempts to break the code has been made.

Lets look a bit behind the scenes;

Assumption: The following skills are used to calculate the TSI value; keeper, playmaking, winger, scoring, defending, passing, form and stamina.

Actual skills (subskills)

Skill levels are not actually 0-20. A player wont jump directly from passable to solid, he will have to work his way up from 6.00 to 6.99 before popping. That means there are 100 different levels of any skill. Subskills is the term used to describe this behavior. The bad news is that hattrick only shows the main skill (presented in text or levels 0-20), his actual skill is hidden. The good news is that there are several ways to spot if a player has a high or low subskill. The one I wont mention is that the subskills are used during matches. So two players with what seems to be identical skills, where the first have high subskills and the other low subskills, the first player will recieve more stars inthe game (provided their form and stamina is also the same).

TSI indicate subskill levels

So a skill is represented in hattrick as x.xx, where x is any number. What we know is that the skill,subskill is used in the formula to calculate TSI. AHA! So investigating the TSI will tell us alot about the real skill, not only the visible value. Thats good to know. Thats an important aspect in order to ern more money than anyone else, because you will know which players are about to pop, and which has just popped. But I have to warn you, this is something you will need time to get the grasp of. lets go o with TSI investigation.

Form and Stamina

These have a huge imact on the TSI. If you are a new user, I reccommend purchasing only players with passable or solid form and stamina. There are just too many unknown factors for you to keep in mind. As you grow more comfortable with TSI I will add some notes in how you can also exploit these skills. But for now lets look at the regular skills only.

What about Set-Pieces?

Set pieces has no effect to a players TSI.

The formula

In a easy world the TSI would be calculated as follows: sum(keeper, playmaking, winger, scoring, defending, passing). But it is not as easy as that.

Weight

TSI does not increase in a linear fashion with skilllevels. This means there is no even increase when going from ie. passble to solid as from solid to excellent. The better the skill, the higher the TSI increase. High skills count more then lower skills.

Lets look at some example 18 year olds, with solid playmaking, passable passing, weak defending and solid stamina. All have passable form for comparison reasons:

Player 1 (TSI: 2080) Keeper 1 Defending 4 Playmaking 7 Winger 5 Passing 6 Scoring 4 Price: 3 999 990	Player 2 (TSI: 1500) Keeper 1 Defending 4 Playmaking 7 Winger 5 Passing 6 Scoring 4 Price: 3 000 000	Player 3 (TSI: 2070) Keeper 1 Defending 4 Playmaking 7 Winger 5 Passing 6 Scoring 4 Price: 3 750 000
Player 4 (TSI: 1370) Keeper 1 Defending 4 Playmaking 7 Winger 4 Passing 6 Scoring 4 Price: 2 800 000	Player 5 (TSI: 1440) Keeper 1 Defending 4 Playmaking 7 Winger 3 Passing 6 Scoring 3 Price: 10 000 000	Player 6 (TSI: 1360) Keeper 1 Defending 4 Playmaking 7 Winger 3 Passing 6 Scoring 4 Price: 2 490 000
Player 7 (TSI: 1220) Keeper 1 Defending 4 Playmaking 7 Winger 3 Passing 6 Scoring 3 Price: 2 200 000	Player 8 (TSI: 2290) Keeper 1 Defending 4 Playmaking 8 Winger 4 Passing 6 Scoring 2 Price: 10 000 000	Player 9 (TSI: 2430) Keeper 1 Defending 4 Playmaking 8 Winger 5 Passing 6 Scoring 2 Price: 8 000 000

Case player 1 vs player 2 vs player 3

These players have _identical_ skills and the maximum difference in TSI is 2080 vs 1500 = 580. This strongly indicate that players 1 and 3  are much stronger than player 2 in playmaking, in other words, their subskill is much better. Consider now players 8 and 9. These have already reached excellent playmaking, but the search criteria is the same. Notice that player 8 has a scoring of 2, but since that skill is quite low, it should not affect the total TSI much. The TSI difference between player 8 and 1/3 is only 210/220. This indicate that players 1 and 3 are actually very close to popping, and player 8 has just popped. These two would have been very good prospects for buying and selling after 1-2 weeks of playmaking training. Players 2,4,5,6,7,8 and would not be good as they would need extensive training for may weeks before actually popping and give you the renvenue you need.

What about player 5?

The open eye will also spot player 5 as a possible prospect. His winger and scoring skills are quite low (weak), but compared to for example player 7 his TSI is much higher, actually higher than player 4 and 6 as well, even though they have better skills. This indicate that the players main skill and its subskill is somewhat higher. There is still too much difference between player 5 and 1/3 to be sure of his fast popping. But he could be a ok choice as well, especially if you could get him quite cheap.

Summary

That concudes the first part of TSI investigation. But this will be a subject I will get back again and again. TSI is a summary of the players total skills. You can use TSI to determine the difference between players and a player hidden subskill.
