Hmm, I'm not so sure about the 4/4 beaming into 2+2+2+2 eighths... I have 
looked at Gardner Read, who doesn't mention it explicitly, but almost all 
examples use 4+4 eighths beaming (except ex. 4.7 and some examples in chapter 
10). 
Grudzinski uses 4+4 beaming exclusively.

I have also looked at some (old and new) scores that i have at home. Most of 
them are quite inconsistent, but the 4+4 beaming rule seems to be predominant 
for eights, only when there are special reasons then a 2+2+2+2 beaming is 
used. I have looked at an old Bruckner edition (mass from ~1890), an old 
Beethoven piano reduction of Fidelio, and some modern scores of masses by 
haydn. The modern ones are really inconsistent, sometimes using 4+2+2 to beam 
a 4/4 measure consisting of eight eigth notes... (But again, when beaming only 
two eighth, it makes sense to do so). The old Bruckner edition exclusively 
uses 4+4 beaming.

However, when the rhythm is 8 16 16 8 16 16 8 8 8 8, then most edition use 8[ 
16 16] 8[ 16 16] 8[ 8 8 8] beaming.

Cheers,
Reinhold
