There are two different versions of Arrow/Flash viewing order on the web. I know that, generally speaking, the sequence of the episodes is flexible as long as the crossovers are done correctly.

But there's one case where the two viewing orders disagree about the sequence of crossovers. This seems odd to me, and I'm wondering if someone here can resolve it.

One version (seen here: ) says the following episodes must be seen in this order:


 * Arrow 3x15: Nanda Parbat
 * Flash 1x18: All Star Team Up
 * Arrow 3x16: The Offer
 * Flash 1x19: Who is Harrison Wells?
 * Arrow 3x17: Suicidal Tendencies

The reason given for this order is that some person, object, or information passes from Arrow 3x15 to Flash 1x18, and subsequently, some person, object, or information passes from Arrow 3x16 to Flash 1x19.

The other version (seen here:  ) says the following sequence is necessary:


 * Arrow 3x15: Nanda Parbat
 * Arrow 3x16: The Offer
 * Flash 1x17: Tricksters
 * Flash 1x18: All Star Team Up

The reason given for this order is that Arrow 3x8 to 3x16 "develops supporting characters" who then appear in Flash 1x17 and 1x18.

(Of course, both of these sequences agree that other episodes could be inserted between the ones listed above.)

As you can see, these two orderings are incompatible. Can anyone clarify whether one of them is correct? Thanks!
