Yes, you should not refer to the NSF FDR anywhere.  That table title is very confusing, because NSF FDR and post-BCP1028 are different things.  Just label it “NSF baseline”.

The left table is BCP 1028, which from what I've understood is the NSF baseline we were supposed to use for muons.  I can remove the "FDR" part of the label, if that's what you mean.

No, you should remove the left part, and any references to FDR.  The cost comparison is between NSF baseline and proposed new baseline.  FDR is irrelevant.

You can read off the costs at NSF baseline from the contingency log, as pointed out in the diff template.

So you want something like this - no associated chart for the before times...?

Hi all,

A number of you have pointed out the difficulty in making an accurate comparison between the MREFC-start and rebaselined cost profiles for your system - thanks for catching this! Since the profile changed (even if only slightly) between the FDR and the MREFC start, we don't have the relevant charts for what the NSF actually distributed.

Our suggestion is that you modify your talks to show only the rebaselined cost and effort profiles. You should quote the total direct L2 system cost from the MREFC start for comparison with the rebaseline, using numbers from the BCP contingency log. But showing the FDR profile could cause confusion/contradiction.

I've updated the L2 talk template in google slides to reflect this change (slides 15,20).

Thanks  -  Hal
