What I *really* *really* know is that there has been no interleaving of pads. The first 24 were on pad a, the last n have all been on b. In thinking about it 61C and 51L were so close together that it makes sense that they were on the pad at the same time. Thanks for correcting me. Glad to hear that a is being reactivated. Burns Fisher
