I think this might work..

@djeddleman took some new readings with the BMP180 sensors using our older tubed pitot, and this is the result.

I love it when data makes a nice line like that.

Given our BMP388 sensors are about 10x more sensitive, I think we might just be ok.  

Still waiting for our boards from @oshpark, but they should be here in 2 days.  I can't wait...
