Suggestion Question: Festive Gift, 17 refined, Mindacos

Link to suggestion for Festive Gift increase from 17 refined to 17.44 refined.
 
 
Case:
 
While my recent suggestion was closed by Mindacos for not being a 5% increase, a suggestion for the Festivizer (the item which comes out of the Festive Gift) was increased from 17 refined to 17.33 refined just 3 days ago with even less buyers than mine at the suggested price.
 
I am fully aware of the gray area 5% change rule, however, I was informed multiple times by members of the community it is okay to raise/lower items valued less than a key by either 5% or 1 reclaimed. I would like an explanation as to the official rule because 5% is not always valid.
 
Here are a few recent suggestions which were accepted with roughly the same price range and price change:
Co-Pilot increased from 16.88 refined to 17.33 refined
Gift Wrap increased from 17 refined to 17.33 refined
Genuine AWPer Hand increased from 18.77 to 19.11 refined
 
Even in recent personal experience I have had a similar suggestion accepted increasing the Strange Festive Wrangler from 16.55 refined to 17 refined.
 
What's more aggravating in all of this is the recent suggestion for the Tour of Duty Ticket increased from 12.77 refined to 13 refined which is a 2 scrap increase, and a 1.7% price change. 
 
Claiming every moderator has their own discretion is not acceptable when it comes to a standardized guideline of knowing whether or not suggestion is valid. Its highly annoying to make suggestions for backpack.tf if all its staff members are not operating with the same set of guidelines.
