Trying to judge which arena crystal is best for the short term

If you were to open a million battlechips worth of crystals a hundred times, the total units would average out and be equal. But no one's doing that, everyone's popping at most a million or a few million at a time.
So I decided to try my hand at some programming, and generated many cases, each of which had a fixed number of battlechips, and drop rates from @DNA3000's last big arena post, and judged which crystal dropped the most units in any particular iteration.
The result I got was surprising(it might be obvious to you, the reader), that the TB dropped the highest amount of units the most number of times. This doesn't make sense to me, cause amounts dropped by each crystal average to be the same value.
There's two possible solutions, I'm understanding the math wrong, or my code is messed up(wouldn't be surprised at that). Consider helping out a fellow Summoner if you have some spare time, and explain to me why I'm wrong, or why the values are the way they are.
Link to code coz entire post would be kinda pointless without it:https://github.com/malreck/mcoc-unit-code-
(Also my first time on github so don't bully me. At this point I'm asking for too much but you've already read so far so I apologize for the horrible variable names and little to no comments)

If you need 15 units right now, you have a better chance at getting that 15 units from the small crystals. If you don't need units right now, you save time by opening the biggest crystals. It's pretty easy to understand.
Clarification is needed as to what exactly do you mean (and potentially mixing up 2 different aspects into a single statement (?)
“highest amount of units” - Yes, well because it is the 25x multiplier (cost/reward) crystal, obviously gives (per crystal) a higher Unit amount per occurrence from the normal or UC crystals (but I’ll assume that is not what you mean).
vs “most number of times” - well, that should actually be the same rate no matter which crystal.
Or do you mean that TB has been yielding a higher percentage of time as the higher of the 2 potential Unit drops (the 3x Units compared to that crystal's more common 1x Units) ?
RE: the fixed “Units” chance rate compared to the breakdown within that of whether it is 1x vs 3x units.
Before this was back to back to back 75 units
If you open more crystals with fewer rewards (I.e. normal arena crystals), the closer to the average you’re likely to get. You’re less likely to get max rewards, but you’re less likely to get non rewards.
If you open fewer crystals with more rewards (I.e TB arena crystals), the results can be more likely to lean to either way above average, or way below average.
Imagine Warlock’s sp2 vs Cap IW sp2. Say you could guarantee that they did the same amount of max damage. E.g. each special did 100k damage if every hit crits.
Warlock’s special has 10 hits, so each one has a chance to crit. It’s quite unlikely for every hit to crit, so you have a lower chance to get max damage. But it’s also quite unlikely for no hits to crit, so you have a lower chance for min damage.
When you take Cap IW’s sp2 however. You have a much greater variation. If your one hit crits, then you get max damage and it’s amazing. But if you don’t crit, then you get min damage. It’s high risk, high reward.
It’s the same concept here with crystals. If you open 5 arena crystals, you are likely to tend to the average. Not super likely to get units out of all 10, but equally, not super likely to get units out of none. When you open 1 UC crystals however, if you get units, you win big, but you’re less likely to come out of it with something.
It’s all about if you want to go for high risk, high reward, or get yourself more likely to come out of it with something.
Either way, on average you’ll get the same over time
1)Initialized several variables for battlechips, number of crystals, some counters
2)Made an outer loop that iterates through the z simulations
3)Outer loop contains three loops, each of which finds the number of units gained from a million battlechips' worth of normal, UC and TB crystals respectively. I've done this computation with a uniformly distributed random number generator and probability weights from DNA's post. At the end of each of these three loops I've added to a cumulative total counter to get avg at the end.
4)After the third inner loop, I've used the ternary operator in java to calculate which of the three crystals gave the highest no. of units(only when three unit drops were distinct) in that iteration, and added one to the corresponding counter.
5)Displayed everything outside the outer loop.
@Scarcity27
Have you taken into account the number of units, or just the frequency?
Does TB give the most frequent unit drops, or the highest total amount?
How may times did you run the code?
2)From 1), total amounts are roughly the same. If we compare the values of units given by the three types in any iteration, TB gives the highest amount of units most often.
3)Admittedly, a few times. I did consider making another loop but I kind of stopped understanding what I was doing at that point.
Also don't feel offended when I don't reply for a while now, it's just bedtime here.
It's pretty late here too, I'll give it a go in the morning (when I can think of a method to write a code that doesn't involve 100 lines of nonsense)
Well, let’s say you’ve programmed in an overall 15% drop rate for any type of Units.
And then within that you programmed it to be a 70/30% split between the lower/higher actual amount of Units (think @DNA3000 analysis was somewhere between 27% and 33% as to what he was seeing for the higher versus just the lower of the 2 Units types).
Your outcome over large enough simulations can only ever tend toward what the inputs were programmed to be. They can’t yield something that is out of bounds from that.
The results of the simulation may not match real-life in the game anyways, since we don’t actually have the real percentages/code that they use for the game, and are only guessing based on very large sample openings.
