YES there is math.... The accepted drop rate is 20%. And assuming you need 50 salvage for a piece and the energy cost is 10...
If you buy 50 refreshes @50c (over several days) that would cost 2500c and give you 6000 energy enough for 600 attempts @10 energy each..... With a 20% drop rate that is 150 salvage. Enough for 3 complete pieces. Making your cost per complete piece 833 crystals. *note expected cost, but it does average out over time*
During double drops the 100c refreshes would net you the same return.
NOTE: it has been said that the drop rate is higher if you have <20 salvage on hand and lower when you have more then 40. Personally I do not believe that, but if you do, your better off farming the first 25 stun guns salvage, then buying 25 salvage from the shop to complete the piece.
600 x 20% (.2) = 120, not 150
2500c / 120 units = ~21 crystals
So in your example each completed piece of 50 units = ~1042c, and the cost for certainty (because in the shop you are paying for a return of a specific amount) per unit is ~5c (just a little over) for Mk 5 Stun Guns (more for more expensive pieces, but significantly less than the example above).
That said, the real difference between our two examples is that in my example, I'm proposing that you can't get a return of a partial piece of gear, and I've factored that in by rounding down after each 'batch' of plays, purchased in 100c quantities. So in my example, 20% of 12 plays is 2, not 2.4. Over time, this leads to a significantly lower rate of return, because I'm eliminating partial units over the course of multiple plays, rather than at the end.
At the moment, my thinking is that this gives a more realistic projection of actual returns and much cheaper cost for certainty.
