Number of sill bolts

[Henry94606]

On the architecture license exam, lateral part, question: on a 13 ft long wall that has 606#/ft unit shear, how many sill bolts of 727# capacity to be placed and at what spacing.
My answer is (606*13/727)=11 bolts
Spacing = (13*12)/11+1=13" o.c.
Is it odd that the spacing being that close ? My experience on the field normally saw them at least 5ft a part. Or perhaps my calculation was wrong ?

It's rare that you would have that much shear in a framed wall and the bolt capacity seems low for this scenario.
IRC is 6 ft, O.C. for most situations.
