Jake,
I do not have the conversion table with me. But rest assured that it is not an exesive amount of tension. he prebend was very slight, probably less than .5inches. The prebend is trivial when compared to the bend induced from downhaul and sheeting.
The problem is with the design of the bracket pure and simple. I suggest that you change yours to avoid any problems. I sailed with the modified bracket with no problems. it is a minor mod. you just have to find a stailess welder/fabricator. Or better yet complain to the factory. it is a desin flaw that should be changed. enough said. It is time to go ice boating!
