Drop System

hello everyone, i would like to know if there is any table related to the drop;
example: https://irowiki.org/wiki/Drop_System

Difference in Base Level Above/Below Monster Level	Drop Rate From Monster
30 levels above monster or more	50%
+ 15 ~ 29	60%
+ 10 ~ 14	75%
+ 6 ~ 9	90%
+ 1 ~ 5	100%
Equal	100%
- 1 ~ 10	100%
- 11 ~ 13	75%
15 levels below monster or more	50%

or have the same chance for all levels ?

 

I would also like to know that! cause i am thinking there is some kind of penalty for level or for map... i am not sure. i have spent 3 bubble gum boxes without gettint any cards, killing 6k+ of the same monstar... no cards... that can't be normal since i dropped 5 cards with 2 boxes in 2 days... since then i got some levels up and just dont drop any thing more in this same map... very weird

 

I don't think so, bubble gum alone would only double the drop, increasing the base from 0.01% to 0.02%, which is still only 1 in 5000 kills.
Still, I believe that the drop rate has a level penalty, as my merchant leveled at Thara frogs all the way from 37 to 67 and didn't drop a single card.
That's probably because the drop rate was influenced by the level penalty, so only for a short while I had the full 1:10000 chance to drop it

 

Aren't the card drop 1/5000 here ?
Thought the 1/10000 was before.
