The truth behind RNG in summoing in VK.

well let me tell you something stright ahead, there is no such thing as a completely RNG summon rate in this game. Why is that you ask?

Any business cares about money more than anything, and would find a way to make it difficult to obtain the desired things as long and as muc has possible. Many people spend lots of money on this game while many others don't. To cut the formalities and jump right into my assumptions, here's what i think: (If you are a free player then you won't understand this)

Every couple of weeks, they release SR's and UR's more than the R's. Approximately around 1 R for every 3 SR's and a UR. They also release other methods for summoning such as "NOW, THE SR / UR SUMMON RATE IS 5 TIMES MORE!" well, do you really think that this is true? I don't think so, for a game to increasingly having more SR's and UR's than before, the proballbity of getting SR and UR is still the same as before. Its all about the daily / hourly settings they set the algorithim codes for the game program to change and lower it down whenever they feel like to. Otherwise, the 79~ UR's and 194~ SR's you could've obtained. assuming its multiplied by 5 times from the "Valkyre Selection DX" after doing the math comparing to the 303~ R's, which means that 194 SR's (excluding the event ones and the ranking reward ones) 194 x 5 =  970 = 500% more

Now, when you come to think of it, the summoing for the usual SR summon is pretty low and you could barely get an SR out of it, that being said assuming its 1% - 5% chance of getting an SR

With the Valkyrie Summon DX it should be around 5% - 20% when actually my 20% buffer cards proc more than the times I summoned on Valkyrie Summon DX.

P.S. ((These numbers are not accurately correct, but when in comparisson with my assumption are a correct small portion of to the total number of cards, but instead in smaller numbers))
