Hi, my pseudo ingame is DeuxExFR if you need more informations about my topic or statistics etc...
I'll explain briefly why i made this experiment : I was farming neural sensors on Jupiter and i droped a lot of Stars. I was asking myself : damn i have too many stars for a little number of sculptures. So i tried to farm these and I watch to the wiki. As said in Gathering Tips : "The Infested Salvage mission (Oestrus, Eris) oddly has the same chance to have Sculptures as full-sized maps, despite being the same size as a Defense/Interception map"
So i farmed this mission quickly and i have been suprised by my luck. I decided to do statistics
Conditions of experience : Mission farmed : Oestrus - Eris between 1:00PM-5:00PM. Warframe : Inaros (mods : Loot Detector, Thief's Wit ). Weapon : Hikou prime (mods : Concealed explosives). Sentinel : Carrier prime (mods : Animal Instinct, Vaccum). Solo mission only
Protocol of experience : Start and spawn in the mission. Progresse slowly in the total map, destroying all destructibles caches and cleaning. Watch to the map for the loot radar. Search for any sculpture
If a Sculpture (or a rare cache) is found, the mission is made normally and exit after the first rotation to obtain the loot. If no Sculpture has been found, the mission is abandoned to accelerate the statistics progress. Once in the orbiter, start the loop again
Any run done, with or without Sculptures : finished or abandonned, is counted as a Run in the total. Sampling will be stoped on a run without sculpture
Results obtained : [Solo run done = 53; run with sculpture = 8; run without sculptures = 45] = 15,09% droprate of sculptures; rare corpus cache found = 2 which drop each : booster credits 30mn, 1 Fieldron, Credits
Personnal comment : It is possible to have a higher droprate because i started the statistics count after droped ~4-5 sculptures on ~9-10 runs. I don't puted into my statistics because i don't remember exactly the number of drop/total run and it could have modificate the stats. I hope this experience will help you to complete your wiki. I give you a maximum of data if you want to reproduce it
If you have any questions, send me a message ingame with my pseudo. Good bye & good farm !
