I've got a huge amount of data on SPs (only buying SPs) - can I email them to you rather than post here? I know you don't need the data on this as well, but I've also recorded which packs had URs and which didn't because it might be interesting to see the distribution of URs - had a very long dry spell and also many clustered together over a dozen packs.

Emailing them to me is perfectly fine. My email address is in the original post. While having records for each individual pack isn't neccesary for determining the drop rates, it is necessary for putting together the streak histograms so once I have your data I may do another update of those.

So, my own small sample is suggesting approximately 6 percent chance per Rare slot on the Arsenal Packs (with the two slots being randomized independently). What are you getting?


The current point estimate from the linked document is 8.19% per slot for APs, and the 95% confidence interval is 7.45%-8.98%.


So, you're seeing about one UR per six Arsenal Packs?

I haven't personally collected any AP data but one in six is about what it works out to for the average of all the data that has been collected (actual average is 16.48% for the per pack drop rate for APs). If you want to look at the detailed data there is a link to a zip file in the original post and that zip file has a spreadsheet which contains all the data.

This most certainly will help. I think this may push us over 4000 samples just from the last 5 days.

I just got to 200 AP (25URs, all listed in the spreadsheet). If you'd like me to switch to a different pack let me know :)

Between N7 day and now, I received 4666 samples which led to us obtaining some results. We can now say that SPs have a higher long term cost per UR weapon card than the other packs, although there isn't much of a gap between the CIs for SPs and RPs.

I would still like more data for SPs, APs, and RPs since getting the sample sizes up to 10000 will narrow the drop rate CIs to a width of about 1%.

I still want more data for SPs, APs, and RPs so no need to switch pack types unless you want to.

Looks like your current AP drop rate is a bit lower than average and the SP drop rate is a bit higher than average. But anyways, looking forward o getting more data.
