Characteristic Improvement - HOUSE RULE
Traveller allows for advancement of skills through diligent training, similarly statistics could also be improved. Just as in the real world, some Travellers invest time in the gym or in course of self study to improve themselves.
A player who wants to improve their physical fitness or their intelligence should be able to increase a statistic through diligent self improvement, be it exercise or memory/mental agility games or just a course of advanced and remote study to improve their education. Similarly characters who want to improve their social standing can spend time getting invited to the "right parties" or being seen at the right "social event".
The normal rules for skills advancement are used, but a "Skills Total" is generated for Physical and Mental statistics:
Strength +Endurance + Dexterity / 2= the Physical Skills Total
Intelligence + Education + Social Standing / 2 = the Mental Skills Total
Rounding up in all cases.
Next the character needs to demine the "skill level" of the characteristic to be trained by dividing the exiting characteristic by 2 and then adding 1, this will give you the equivalent target skill level.
It will take the current Skills Total (either Physical or Mental) + the Target Skill Level, in weeks to improve that statistic by one point.
Not all characteristics can be improved in all environments; it is unusual to be able to improve your Social Standing whilst in jump space for example.
In any case no characteristic can be improved by more than 50% (round down) of its value at the end of character generation. e.g. STR 7, could be increased by up to 3 points. Nor can a characteristic be increased beyond its racial maximum.
No characteristic can be improved past the point at which aging impacted it. e.g. a character with END 8 reduces their statistic to 7 due to aging, it can never be raised above 8 using Characteristic improvement, further aging effects do not affect the maximum characteristic further the maximum remains 8 for that characteristic.
Instructors can improve learning times, but, only by 1d2. Their equivalent skill level is their statistic divided by 2 (rounded down).
As with regular skills improvement a character can only train in one "skill" per week (e.g. a skill or a physical characteristic or a mental characteristic).
Example:
Alexander Jamison , STR 6 DEX 8 END 8, wants to improve his STR, his Physical Skills total is 11 (22 for the stats over 2 is 11), with a target skill level of 4 (6/2 +1) means that Alexander will have to spend 15 weeks in the Gym to improve his Strength.
