If it isn't in writing, then submit the paperwork for everyone that was earned and see what comes back. I was always under the impression that on could theoretically get four rings out of a series if they were fortunate enough to be in a position to shoot 298, 299, 300 and have the 800 series, plus the watch that goes with whatever it takes to earn the watch these days.
I do know people that have gotten a ring for 300 and 800 plus an 11-in-a-row plaque on the same set, but it has been a few years...
