I have found a way to use my old graphics calculator for Destiny. I worked out a formula that determines the time taken and amount of stuff earned for any number of strikes. Huge shout out to Beeray784 on reddit and DPJ on you tube for the values that have been obtained (links to pages will be below). Pro numerals used are as follows: A- number of strikes T- time taken in minutes to complete the strikes (this value was found from the average time on each strike map in Beeray784's reddit post) B- the amount of blues earned during the ROC strikes C- the amount of blues (from the ROC strikes) decrypted that became legendaries L- amount of legendaries obtained during the ROC strikes E- amount of exotics obtained during the ROC strikes The formula is as follows: 1. ClrHome 2. Prompt A 3. A * 8 -> T 4. A * (632/400) -> B 5. B * (2/100) -> C 6. If C < 1 : Then 7. Disp "CRYPTARCH IS STILL AN ASS" 8. A * (20/400) -> L 9. A * (8/400) -> E 10. Disp T, B, C, L, E 11. Pause 12. Stop Note: You may change the pro-numerals if you want. the "*" and "/" is the notation used for multiplication and division respectively. -> means "store as" (aka your STO button). The 1. , 2. ... is the line number (just hit enter after you have completed each line). All words such as "If, Then, Prompt ..." are words found under the button "PRGM" button on the calculator. the words "disp" and "clrhome" are short for display and clear home respectively.

I have been away from Destiny forums for 20 hours and somehow i am trending. Unfortunately sometimes this formula does not work when you display the text: "Cryptarch is still an ass" first rather than displaying "T,B,C,L,E". I would advise to move lines 6 and 7 below line 10 to ensure this to work. Also, there is a much simpler guide for this if you don't have a graphics calculator. It is the following: 1. find how many strikes you wish to do (i will call this number A) 2. A x 8 = Time it takes to complete in minutes 3. A x (632/ 400) = amount of blue engrams 4. amount of blue engrams x (2/100) = amount of legendaries the cryptarch gives 5. A x (20/400) = amount of legendaries 6. A x (8/400) = amount of exotics Just use the above values in a calculator and you will get the same results minus the cryptarch still being an ass. You'll have to say that line :) Keep up the responses guardians. (I do count as a warlock as my main is both TITAN and WARLOCK, i play equal amounts on both).
