Hello all, I seek PFS advice from experienced PFS GMs and/or officials,
I recently got into an argument with another PFS GM about determining APL. My stance is that the Pathfinder Society Roleplaying Guild Guide (currently v7) stands as the sole source on this subject and that it trumps other sources. The first paragraph of "Determining Subtiers" is what I would use to determine APL in a PFS game:
"In order to determine which subtier a mixed-level group of PCs must play in, calculate the group’s average party level (APL). Divide the total number of character levels by the number of characters in the party. You should always round to the nearest whole number. If you are exactly at 0.5, let the group decide which subtier they wish to play."
My colleague's stance is that APL should be calculated according to rules on encounter design (found on this page):

notably, the following passage:
"Determine APL: Determine the average level of your player characters—this is their Average Party Level (APL for short). You should round this value to the nearest whole number (this is one of the few exceptions to the round down rule). Note that these encounter creation guidelines assume a group of four or five PCs. If your group contains six or more players, add one to their average level. If your group contains three or fewer players, subtract one from their average level."
According to my colleague, this position is espoused by many online GMs who use 2010 posts made by Mr.Joshua J Frost:
"Groups, tables, sessions, etc normally have to calculate APL and play the appropriate sub-Tier. So, even at level 1, if you were a table of 6 level 1 characters, your APL is still 2 and that means you still need to play sub-Tier 1-2." (conversation found here: http://paizo.com/paizo/messageboards/paizoPublishing/pathfinder/pathfinderS ociety/general/shoppingWithPrestigePoints&page=1#48)
As you can see, Mr.Frost's posts imply that APL should be calculated according to the information found in the section on Encounter Design.
It seems to me that the information on the Encounter Design page is mostly incompatible with the Pathfinder Guild Guide's prescription for calculating APL and determining subtiers. As such, it should not merely override Encounter Design rules for determining APL when necessary but replace those rules completely in the context of PFS.
In our small circle of players, a lot of GP for out-of-tier rewards are at stake: for a season 0-3 scenario, the guild guide would have a table made up of 4x level 2 adventurers, 1x level 1 adventurer and 1x level 3 adventurer (average 2 therefore APL 2) play low tier whereas my colleague would attribute them an APL of 3 (average 2+1(as prescribed by the rules on Encounter Design)) and allow them to choose their subtier.
Thank you in advance for your help, our Lodge's balance depends on these results!
P.S. In addition, we have a word/rule-lawyer or two who would argue that the wording in the guild guide, "In order to determine which subtier a mixed-level group of PCs must play in" implies that a group on non-mixed-level PCs are exempt from these rules, and a group of 6x level 2 adventurers would have an APL of 3 (as per Mr. Frost's recommendation) whereas a group including 4x level 2 adventurers, 1x level 1 adventurer and 1x level 3 adventurer would have an APL of 2 (as per the Guild Guide's recommendation). So basically I need a consensus as to whether PFS GMs should [always and only rely on Encounter Design rules to calculate APL] or [always and only rely on the Guild Guide for calculating APL in PFS].
