He said he doesn't want to make reports weekly and I understand him. If I were developing the physics I wouldn't want to say "This week I'm working on XXX" then next week say "The XXX idea turned out impossible" then next week "I'm still trying to figure how to do XXX", and so on. He said he only makes reports when theres something to report, so we can understand this two and half months of silence as:
a) Carcass Deformation turned very hard and still not finished.
b) Silently finished carcass defirmation and started on suspension/VW SC.
I think we all hope the second option is right.
