If you buy the FG crowd sourcing, 6/ $100MM is about the guess of what it'll take.
This is closer to the Tex negotiation than the Werth neegotiation. With Tex, the initial 8 / $160MM was not enough to preempt the market, but it set the lower bound of the negotiation. With Werth, the high offer preempted others looking for OFs, especially places where Werth might have been a better fit.
