Guild Wars 2

Question is based on guides posted here:
http://www.guildwars2hub.com/guides/basics/complete-guide-guild-missions

How can we get 12 commendations per week? In our guild, when we did Tier 1 bounty, we did get a chest and 2 commendations for the first time we killed the bounty (even before we killed the other target[s]). The merit comes after all targets are defeated within the time limit. However, after doing Tier 2, no chest nor commendation was given. Note that the mission is done for the first time and not affected by the “7PM EST Saturday window” limitation.

According to gw2hub link above, we have the following commendation rewards:
•Bounty – (Tier 1) 15 Merits, (Tier 2) 20 Merits, (Tier 3) 25 Merits – total of 6 commendations
•Trek – (Tier 1) 5 Merits, (Tier 2) 7 Merits, (Tier 3) 10 Merits – 0 commendation
•Guild Challenge – (Tier 1) 30 Merits – 2 commendations
•Guild Rush – (Tier 1) 15 Merits – 2 commendations
•Guild Puzzle – (Tier 1) 30 Merits – 2 commendations

For a total of 12 commendations and 4.5Gold per week, assuming the guild can complete ALL those categories and ALL tiers of each category.

However, like I said, doing Tier 1 nets us the merits, and rewards (1 chest, 50silver, rares). But Tier 2 produces nothing, granted, we failed it the first time we tried. Do we need to complete Tier 2 to get the commendation? Because in Tier 1, even just killing 1 bounty and not killing the other one gives us commendation, rare and silver.

TL:DR
So, is it really possible to get 12 commendations per week (and on a side note, 4.5G per week) or not? If so, can anyone give a link or guide?

I checked Dulfy, and it says
“You earn 2 Guild Commendations per Guild Mission category with a weekly reset.” – but never clearly specify if it’s applicable to all guild mission (gw2hub says Trek don’t give commendations) nor whether Guild Mission gives commendations per tier.

I checked gw2hub, and it says
“The potential then, once you have all five Guild Missions unlocked at all tiers, is to earn over 4 gold per week and 12 Commendations (I don’t believe Trek offers Commendations). "

you get 2 commendations per mission type per week except treks which give no rewards at all, not even a chest :O

so 8 commendations a week after unlocking all missions.

im not sure where the 4g a week is meant to come from but assuming each mission has the same prizes then 2g is as high as you can go without taking rares into account

Thanks! The 4.5G comes from 50s per Mission.
Bounty = 50s x 3 = 1.5G
Trek = 50s x 3 = 1.5g
Rush = 50s
Challenge=50s
Puzzle =50s

So for all, it’s 4.5G (1.5 + 1.5G + .5G + .5G + .5G)

At least, that’s how I interpret the post from guides, but now I know it’s incorrect. Tnx again!
