Those delays had considerable overlap with each other, so adding is not accurate. For instance, much of the time we were waiting for zynqs, we were also waiting for Lasp tests/specs.

Hi Andy,

        We have some issue getting a consistent story on the SRTM delays:

on p. 17, you say these 2 things:

"COVID caused ~9 months of delay in progress on hardware and firmware
development (reduced efficiency of remote work), as well as ~12 month
delay in feedback from LASP specs / testing"

"Supply chain disruptions caused ~8 month delay in availability of Zynq
FPGAs needed for assembly of v1.5 sRTMs"

        If I add those together, I would end up with a total "World Events"
delay of about 29 months.  With 20 working days per month, this would be
29*20 = 580 working days.  Yet, in my L2 talk I give a range of 324-356
days, since that is what I find adding up the delays from the 4 "COVID
BCPs".  So, I think the COVID BCP preparations did NOT count the LASP
delays as COVID-related.  In which case, we need to be consistent now
and not count them that way.

        Regards,
                John
