The upshot is that our
experiment_triggered
event often appears to have a later timestamp than the subsequent actions which we'd be measuring in the experiment, resulting in the data being excluded and most actions appearing to have occurred zero times
There are two potential options which come to mind: 1. set a -24h delay on the conversion window - don't know if this is intended, but it does work, though it would also include some events from the previous day 2. truncate the timestamp of all
experiment_triggered
events too - the main issue I could foresee is that we may have evaluated multiple variations for the user on the same day, due to our React app loading attribute data via several API calls - it applies the attributes as they become available Maybe there's others we haven't considered too?
On (2), if multiple variations have been recorded for the same user, it looks like GrowthBook will either take the first occurrence, or treat each occurrence separately - depending on the attribution model set on the experiment

Both of those options would work. Negative conversion delays are meant for cases where the logged experiment date might be after the metric conversion. Most commonly used for things like sessions, but it would work for this too. Just to clarify the "multiple variations" part, if the user sees multiple different variations (e.g. A and then B), we remove them from the analysis completely. If they just see a single variation (e.g. B), then the attribution Model determines how we treat multiple exposure events.

ah great okay, so it's pretty safe to truncate
it seems like option 1 would be less likely to include incorrect/old data, as it's at least limited to being on the same day
before/after
Seems to work well! Thanks for the info 🙂
