Evaluating the coin efficiency of Mysterious Pouch 4 (Poverty Dragon)

Since the implementation of coins in the event, we have seen various strategies for coin-farming. Barring multi-pc strategies, I will like to put forth an evaluation of the Mysterious Pouch 4 and why I think there should be a slight buff of 5 coins.

<Screenshot copied from event thread>

Lets compare Zak and HT with the assumption of average coin yields per pouch.
An average 12man HT takes 1.2hrs to complete, with an average of 25 coins. This equates to 1.74 coins per hour.
An average 6man HT takes 1.7hrs to complete, with an average of 25 coins. This equates to 2.45 coins per hour.
Comparatively, an average 6man Zak takes 0.5hrs, with an average of 15 coins. This equates to 5 coins per hour.
Stronger parties can attempt 4man Zak and this equates to 7.5 coins per hour.
But of cos, comparisons of Zak and HT are problematic due to differences in value of boss loots.

Lets compare PB and HT with the assumption of average coin yields per pouch.
A 30 man PB takes ~2hrs, with an average of 180 coins. This equates to 3 coins per hour. Barring differences in boss loots, MW20, MW30, FS, etc.

Comparing loot values between bosses are always problematic. But the trend of preferring Zak over HT for coin farming has been present in the community. Pls refer to owlrepo for prices of Gen20, Gen30 and MW20.

Thank you for coming to my Ted talk.
