[FTC]: "Ring It Up" scoring clarification

[smcmahon]

So let's say we score three rings across the middle row of pegs.

10+10+10 = 30 + 30(line bonus) = 60

Now what if we can score six rings across the middle row of pegs, basically double-scoring each peg. Does that score for 120, or 90? I guess: does the line bonus score twice because we technically have two "lines" of rings?

10+10+10+10+10+10 = 60 + 60(line bonus x2) = 120
or
10+10+10+10+10+10 = 60 + 30(line bonus) = 90

We haven't competed yet, so I'm not quite sure exactly how that would be scored. I did look through the Q&A, but didn't see anything similar asked or answered.
