"Strictly liable" means, I think, that you are sure to get about $150,000 US in any case, no lawyer needed. That would imply that you would only involve a no-win, no-fee lawyer when looking for a payout in excess of about $215,000, since 70% of that would be about $150,000, putting you back where you started.
For 130,000 SDR the number would be about 186,000.
(You need to divide X by seven and then multiply the result by ten to get the amount needed to yield X when thirty percent is deducted from it; it's more than the $195,000 or 169,000 SDR that you might first guess at.)
