This seems slightly redundant. Either you use literal 3 all over, or set the DefaultOptLevel on a higher place. Also, this is not the "default" level, but the fall-back level for high levels, maybe a better word would be "MaxOptLevel", if there isn't one already (I don't know).
If there isn't, than maybe you could create a MaxOptLevel on a higher level and change all comparisons "OptLevel > 3" for "OptLevel > MaxOptLevel".
