Well, the only reason to consider the range of candidates is to estimate the range of voters. So what, really, should R1 be? Zero, because I'm not outside the range of voters, and the range of _voters_ is what I really mean. The most distant (winnable) candidate is needed to estimate how far the voters extend from me.
