One thing to be aware of is that latent hits, via the Queue Time "qt" paramter, have a maximum delta of 4 hours: "Used to collect offline / latent hits. The value represents the time delta (in milliseconds) between when the hit being reported occurred and the time the hit was sent. The value must be greater than or equal to 0. Values greater than four hours may lead to hits not being processed." Would be nice if that delta time could be greater than 24 hours, eg. a human approves that a low-volume contact form submission isn't spam and that hit is tied to a GA goal.
