That's actually a glitch that I am fixing... desperately! Some of the backend APIs are down due to excessive requests, so I am trying to get them back up.
I was wondering the same since the Crown–rump length (CRL) measurement only has two points. One would think the spine should be included for an accurate measurement. However, that must be accounted for already. See also, "3. First-trimester fetal measurements" and "4. Assessment of gestational age" here: http://onlinelibrary.wiley.com/doi/10.1002/uog.12342/full
Love this. I managed to get a pretty stable orbit by using the right angle and velocity (by chance). Highlighted in yellow: http://i.imgur.com/OOaTLMP.png
It ran for several hours like that and never deviated from the original "circular" path. Unlike the other attempts, which were all much more elliptical. I guess that's kind of how planets would stay in a stable orbit though, having the right distance and speed for their mass.
I'd think this could be prevented by a) stop giving out order numbers via chat and b) require customers to request replacements (or at least confirm them as you've suggested) by logging into their account.
There are a lot of people like you even in the US. Cost of living in California is part of the issue. Tech companies could find the talent for less pay if their workforce was located outside the most expensive areas.
