Hi John,

Thanks for spotting this.  As much as possible I would like to avoid 
these 67% numbers.  So instead I have removed that text everywhere and 
changed the number in J7 to 1088 (4x272).

For the ADC, I've changed the text to "Direct cost reflects 66.2% US 
cost share." as there the cost needs to include the NRE, so scaling down 
the number of parts doesn't work.

Now, for the lpGBT and VL+:

-lpGBT: according to the BOE 41400 are needed.  US share is 55.4%, so we 
should want 22936.  But the sheet you sent has 28140?  (I was not able 
to reverse engineer where the 28140 comes from.) For now, I changed the 
number to 22936 and added in the comments: (US pays for 55.4% of total 
needed, ie 22936 of 41400)

-VL+ should be 7645 rather than 9246 you listed.  So I did the same 
thing for now.

BTW, there's a mistake in the BOE: it says that the optics costs are 
escalated, but the resource used is no escalation.  I think no 
escalation is correct, certainly for lpGBT.

Best,

Gustaaf
