I finally tried a different bevel angle on a 2-inch thick plate and it worked better

I was welding a patch on an old boiler in a plant here in Toledo, and the spec called for a 37.5 degree bevel on the joint. I've always just set my grinder to 30 degrees because that's what I was taught, but this time I actually measured it out. The fit-up was so much cleaner, and I used about 15% less filler rod on the root pass. It just sealed up smoother with less grinding afterward. Has anyone else found that hitting the exact bevel angle makes a bigger difference than they thought on thicker material?
