Roger, Unless there is something truly abnormal about the stringing scale -- and I don't think there is -- this plate is not cracking due to the string tensions through this area. By this I mean that adding the string tension is the last straw. There is not normally all that much stress on the plate through the upper tenor/treble sections relative to the strength of the iron. I suspect there is something else happening. Tell us a bit more about the precise location of this crack, where it starts and where it ends. Perhaps you could also tell us how the plate is mounted to the rim, the type and location of any nosebolts in the area and what you did to lower the plate for added downbearing, etc. Regards...and our condolences...
