OK, I've searched and I know I've seen it before but I can't find it again so...
What is the equation to calculate the strength of the RIS?

BTW, when you look up 'Shields' in the Pedia it does not mention the RIS.
Also, is there a way to 'search' the Pedia?

It is defined in this file.

The value is the minimum between (a) 20, (b) the number of RIS ships within 0 jumps, and (c) the square root of [the number of RIS ships multiplied per 7].
This means that up to 7 ships you get shield = number of ships, and from then you use the sqrt(7*N) formula, which reaches the maximum at 58 ships (but it is already at 19 with 52 ships, and is gets 15 with 33 ships).

The other questions, IDK.

Thanks for the info
