BUBD Shirt: Collar band Assistance

This is my first ever boy's button down shirt. I am taking it slow so that fatigue doesn't cause mistakes. But I am at the stage where you pin the collar band on the shirt and have a question. My band seems way too long. When you place the band and align the dots with the folded edge of the button placket, there should be 1/2 inch excess at each end from dot to edge of band fabric. Then you should ease the collar band between all the matching notches, seams etc. However, I feel like I have a lot to ease. Basically I have an entire 1/2 inch to ease which would require a TON of clipping against the neck curve to get it all in. The instructions say clip as little as you can. I need to clip a ton to accommodate the curve and extra ease on the band. It feels like too much extra. When I just pinned the collar at the dot-folded button placket edge and laid it out without matching center, etc, the band lays perfectly against the neck edge but the collar extends a full 1 inch past the folded button placket edge (and therefore 1/2 inch past the correct ending point). Is there supposed to be that much ease, clipping for the curve, etc?
