Note the following about "in which". (The same things are generally true for "preposition + which".)
• Like "which", it can follow a comma.
("in" + "___, which..." = "___, in which...")
This type of modifier follows exactly the same rules as "___, which...", from which it's derived.
(Note the use of "___, from which..." in that sentence.)
• Unlike "which", it can also NOT follow a comma.
("in" + "___ that..." = "___ in which..."
This type of modifier has the same freedom as the modifier from which it's derived ("___ that..."). <–– I used such a modifier in this sentence.
As you may know, "___ that..."——and, by extension, "___ in which..."——has A LOT of freedom. Check out the distance between "a standardized way" and "...that..." in #50 in the OG Diagnostic chapter. Quite a bit of distance indeed.
The problem at hand falls into the latter category.
