Narrative:

After push and taxi out of den; we needed to deice. We were assigned pad. After we checked into frequency; we heard one of our jets get his deice information. The deice crew reported type I...time....' we asked if they were shooting type I only. We reported ATIS calling for -18 degrees C with light freezing drizzle. Another deice coordinator came up on frequency and started splitting numbers and that his computer was stating that we had holdover times to 31 mins. I then got on frequency and asked where the computer was getting these numbers; with a -18 degrees C and falling precipitation. We then asked for a follow-up type iv -- which we got. The same man came up on frequency and stated that with a type iv; holdover would be 120 mins. Again; not the time we have in our fom; but workable. Why are we allowing the deicing; with precipitation falling of type I only? Again; you could easily see the falling moisture; ie; we did not need ATIS to state this condition. We did have 2 jets taxi out with only a type I. I am sure that we all know better; but things do happen for all kinds of reasons.
