You have probably see several of the Orange and LA County housing tracts that were done piece mill by the framing contractors.  Remember how they use to and sometimes slot cut the sill plates because it was faster to erect...time is money one house a day...
That; along with laborers that were told not to or were to lazy to change drill bits as they were drilling away on wood members.  Holes around sill plates were usually 3/4 -1" while using 1/2" anchor bolts.  This was confirmed after Northridge during site visits by several people..............so new City of LA interim memo.....now code.
 
Also at several apartment projects I and others investigated in the San Fernando Valley found sill plates split lengthwise along the AB line.
