The six (6) footballing skills of a CyBloc are: Tackling, Passing, Dribbling, Crossing, Shooting and Physical. CyBlocs are all born with a base rating for each skill (i.e. at Level 1), which is randomly generated based on their Classes.
A CyBloc is given 1 free skill point at every level (including level 1) up until max level at 100. These free skill points can be assigned to any of the CyBloc's six skills, up to a maximum of 60 skill points per skill.
A Level 1 CyBloc with Tackling rating of 40 will only be able to achieve a maximum Tackling rating of 100 (40 + 60).
Whenever a new CyBloc is minted, all of its six skill ratings must fall within a defined range depending on its Class. If a new CyBloc (at Level 1) does not have a total sum of all six skills within the relevant range, its skill ratings will be re-rolled until the sum meets this requirement.
As shown in the table above, the upper limit (maximum) for the sum of all six skill ratings of a Legendary CyBloc at Level 1 is 325 and at Level 100 is 425. Using this maximum possible sum value of 425, an overall rating can be determined by summing up a CyBloc's skills and then divide it by 425.
If the sum of a CyBloc's skills is 340, its overall skill rating would be:
340 / 425 * 100 = 80
