I figured It would be usful to understand how I've structured my posts on various pb's so here it is

1Number of times I spawned the Pb
2Difficulty Farming Level:
A global score attached to the following terminology is given to the Pb. After that a better estimate of the time it takes on average to gather a pattern is given.
Very Easy (4 Completes/h ish or more)
Easy (3 Completes/h ish)
Medium (2 Completes/h ish)
Hard (1 Complete/h ish)
Very Hard (1 Complete in 2ish hours)
Super Hard (1 Complete in 3ish hours)
WTF!? (1 Complete in 4ish hours or more)
Myth... (1 Complete in 5ish hours or more)
3Pattern Drop Rate:
Total % drop rate followed by individuel drop rates of pattern pieces
4Boss Spawn %:
How often the bosses dropping patterns spawn
5Notes:
Special notes if any
6Location
As Simple as it gets
7Dropped
There are 2 datas you'll find here:
The first, and most important one, is the frenquency of the symbiant appearing in the loot table (Exemple: In 10 spawns XYZ sym appeared in loot table 4 times)
The second is the total % compared with the total amout of syms gathered from the spawning (Exemple: In 10 Spawns ABC Sym dropped 15 times and in total 30 syms dropped meaning 50% of it was ABC)

Updated my guide to better reflect difficulty levels on gathering patterns for thoses that have low drop rates
Very Hard will now be (1 Complete in 2ish hours)
Super Hard will now be (1 Complete in 3ish hours)
WTF!? will now be (1 Complete in 4ish hours)
Myth... will now be (1 Complete in 5ish hours or more)
As of such some pb's will have to be readjusted and might vary a bit, I'm updating my information and using better calculations to more accuratly reflect the given numbers but it will take some time.
In the mean time the tools available should give you a resonable amout of information
Yet another update is slowly coming to my posts. Refer to first post to see the changes.
Please note that it will take extensive amounts of time to rework all my posts since it requires me to redo the work I already did that took me 8months. So, it might take a few months or maybe years depending on the time I have. In the mean time most of the posts will be using the old data sheets whice are still fairly exact
Small update.
Modified the way the symbiant layout is.
Categories are now defined as %, layout slighty changed also
P.S I might do a few more updates on my posts this summer. I dunno
