I will admit to not reading the Hacking dramcon -- the most reasonable place to find the information for which I was searching. I did run a text search for the string "internal access," though, so I wasn't a complete duffer. Thanks for the pointer. I'll read through the dramcon description when I get home this evening.
Always using the Internal Access times is good, but the real meat of that ability is the 'fallback' Power Rating boost when you already have Internal Access since this condition should be the baseline state for a Runner.
