"If you can bring that average down to roughly 1 second, you won't be hurting. That time won't win any speed awards but is a good place to be, especially if you are working on other aspects of shooting too."

1 second , down 0 on a IDPA target at 7 yrds from concealment might not win any speed awards in your factory sponsored rarified air but out here in the real world that is extremely fast.
As GJM stated, 1.7 is very solid and could be pared down with practice I am sure.
FWIW
