The aegis Astral skin has the Speed option twice as free as bonus mods, however the Speed option state:
The aegis’s base land speed is increased by 5 feet. This customization can be selected up to five times. Its effects stack
Now does this mean the option can be taken a total of five times flat and stack or that it can add a maximum of 5 times, in addition, the 2 Speed mods that the Aegis' Astral Skin already come with?
So, Astral Skin max speed with CP:
Speed x5 = +25 feet to base speed, or
Speed x7 = +35 feet to base speed
