Answers to a few questions below.
My strategy was pretty simple, it was essentially:
- place 20 bus station skimmers and then pick them up when I had enough details to get to CS25
- then place 20 gas station skimmers and then pick them up when I had enough details to get to CS100
That would equal 80 attempts with a wiggle room of 20 to account for any failures, as my aim was to max out CS in under 100 attempts.
In reality I lost a few bus station skimmers but had enough overall details to still get to CS25, so I saved a few attempts not having to pick the lost ones up. I had around 200 details per skimmer. This part only took a week or two.
I also lost a few gas station skimmers and decided to replace a couple, but in the end I needn't have replaced them as those bad boys are super reliable generally and I cashed a bunch in when I had enough at over 2,000 details each which got me to CS100. This part took 238 days.
29,629 card details collected overall.
Right before I picked up the skimmers for both steps I churned out 50 consecutive graffiti crimes to hit a big crime chain.
The cool part was picking up the first 2,000+ detail skimmer and watching my CS rocket up by 11 levels at one press of a 4-nerve button lol.
The best tip I can give is to read Emforus' guide, as I used all of the info on there to formulate my plan.
If someone wanted to beat my score I would advise trying maybe 10-15 bus station skimmers to get to CS25, then placing 20 gas station skimmers and never replacing any that you lose. Then waiting until you get a stupid high amount of details on each skimmer (5k+?) and cashing them in. Or go hell for leather and wait for 1 skimmer to hit 29k details before just cashing 1 in to get to CS100.
I definitely think it's possible to max this crime in 50 attempts or less if done with militant detail and a humongous amount of patience!
