It seems to me that the engine does not magically stop if the valves are a bit more tight or loose than spec so I was curious about the acceptable range even if BMW does not publish a range.

Also, what's with the use of one feeler gauge for both valves? I'm having a hard time wrapping my mind around what that gets you vs. doing one valve at a time.
Using a single feeler between the two valves allows you to feel if one is tighter than the other. If you pull from the middle the tighter valve will drag more and you will know they are not the same.

Read this, it might help:
