Question on Drop Rate

I had a look at how different the drop rates turned out for each of the types of boosts

	Coefficients	actual	promised	diffference	diff / promised
Intercept (base)	49.614	1.000	1.000	0.000	0.000
Greed pendant	0.831	0.017	0.000	-0.017
Mutant Ribbon Pig familiar	18.601	0.375	0.600	0.225	0.375
2 x 20% drop equips + Greed pendant	10.831	0.218	0.400	0.182	0.454
8 x 20% drop equips + Greed pendant + 20% additional drop on Greed	69.386	1.399	1.800	0.401	0.223
8 x 20% drop equips + Greed pendant + 20% additional drop on Greed + Wolf Underling familiar	187.636	3.782	3.800	0.018	0.005
Greed pendant + 20% additional drop on Greed + Wolf Underling familiar	58.786	1.185	1.200	0.015	0.013
Mutant Ribbon Pig familiar + Greed pendant	17.071	0.344	0.600	0.256	0.427
Greed Pendant + 2x drop USE coupon	34.986	0.705	1.000	0.295	0.295
Showdown	10.275	0.207	0.300	0.093	0.310
Showdown + Greed	9.486	0.191	0.300	0.109	0.363

i just made a spreadsheet looking at how much lower the boost is than what is promised

wolf underling appears to have very decent performance. congrats to all who spent the hundreds of millions on it. the drop off may be explained by the drop equips. if so, it may in fact give over the promised 100pc.

a possible theory: the boost is only lower for those which boost both items and meso. wolf underling apparently only boosts items and not meso.
so perhaps something is wrong with their RNG, each drop is not calculated individually and independently of each other or something like that.

well if anyone has any of these others which only boost items, perhaps try them next time. mingu and sr bellflower root appear to be best bet since they go anywhere. I think they are both in mulung/ herb town

Increases Item Drop Rate

+30% Item Drop Rate: 16. Ghost, 30. Jewelery, 96. Sr. Bellflower Root
+50% Item Drop Rate: 10. OS3D Diver, 11. Strange Pig (on Victoria island), 38. Sentinel (in Orbis), 45. Black Ratz (in Ludibrium), 45. Dark Cloud Fox (in Mushroom Shrine), 62. Leader A (in Showa Town), 70. Rococo (in Edelstein), 73. Sparker (in Aquarium), 80. Mingu, 85. Grizzly (in Mu Lung), 98. Homunculus (in Magatia), 119. Dark Yeti (in El Nath)
+100% Item Drop Rate: 100. Wolf Underling, 100. Black Kitty (from halloween)

Sorry it took me so long to realize why showdown was so low. I forgot about Assassin's mark and Night lord's mark. Those activate on their own and a couple can kill off a monster before they are hit with showdown.
