I always use 60% bump and 40% rebound. Yeah, that calculator is a little awkard and is for an a-arm suspension front end . I have a straight axle. For the motion ratio, I jacked up one front wheel 4". When I did that the shock moves only 3". So I used a .75 motion ratio. Not sure if this is completely accurate. I based my original spring choice off of the sprint car. We used 250 to 300# springs on the front of the sprint. Of course the sprint only has about a 300# corner weight in front. The hot rod has a 525# front corner weight. So I decided on a 225# spring. It is not uncomfortable to drive and handles well, but could be a little softer. I was just looking for some confirmation before I spend another $200 or so on new springs.
