Please make it clear that the calculator is not necessarily giving accurate quotes
I was just using the calculator today to figure out how much to charge my customer for shipping. I went in, used the calculator, and got a "rate" of $33.88 for a 30 pound package to 48315 zip code.
When that customer actually placed the order and I went to create the label, I entered a 30 pound package weight to the same 48315 zip code the rate was $37.73. That's a pretty substantial difference, and when I contacted support they told me "so the calc does not send the full api call when requesting the rate" and that you can't really rely on the calculator for a truly accurate quote.
I think this message needs to be clear - I don't see any mention whatsoever on the calculator telling us "hey, just so you know, these rates are not necessarily accurate" That would be very very helpful. Save me from losing money on my shipping.

Thank you for your feedback!
