shut, and the channel finds other things to do
With nothing shipping and nothing being answered, the sourcing channels went quiet and the analytics channels filled up instead. This is the third year running that February has produced the room best technical conversations, apparently because everybody has time and nothing to buy. The main event was a re-examination of how the room reports content figures.

What happened
- The analytics channels agreed to report content as a range with the lab and method attached, retiring the single-number habit for good.
- Inter-lab variance was quantified from three years of the room own submissions, which is the first time anybody had put the numbers together.
- Medutest and VendorInvestigate were both referenced in the summary, one for results and one for domain work.
- A member with a three-week gap in supply asked what to expect and was given experience rather than reassurance.
- WuXi TIDES and Homopeptide were compared on documentation rather than price, which is a conversation the channel could not have had in 2024.
