This may or may not be errata so please bear with me.
This all started because my girlfriend is using the Street Samurai from the SR4A Core Rulebook exactly as written. The pre-generated character can be found on page 110.
From the rules for cyberlimbs found on pages 343 the base stats of a customized cyberlimb start at 3 (str, agi, body) which can then be increased at increased cost and use of slots in the arm (which has a Max of 15 per the rules).
The problem I am having is that it appears whoever created the character seems to have used the character's meat stats (agi 5 and str 5) and then added the enhanced abilities scores.
Per the pre-generated character she has +3 agi and +2 str in both arms. Per the rules this takes up 5 slots for the agility and 4 slots for the strength boost (each starting at 3 with agility increased to 8 and strength increased to 7). The stats cost 9 slots plus 4 for the armor (2x the armor rating in slots) = 13 of 15 slots used. Her left arm has a small smuggling compartment (unsure of how many slots this takes as only the large smuggling compartment seems to have a slot number assigned) and her right has a spur and a shock hand.
Fingertip compartment (capacity of 1), smuggling compartment has 2, and large smuggling compartment has 5. So considering the the compartment takes 2 slots takes up the entire arm's capacity of 15.
For her right arm however she should be way over. Per page 345, a retractable spur takes 3 slots and the shock hands take up 3 as well. That puts per total slots used to 19 (4 over).
All this because she wanted gyro stabilization. Is my math right and am I looking at the right sources?
