The data from Trackr is likely accurate but highly confounded, so I wouln't take their insights too seriously. The people who apply for second internships tend to fall into two buckets. Firstly, people who didn't convert and are therefore on average weaker candidates. Secondly, it's the people who did internships but are applying again only for the top roles and hence have lower success rates, e.g. did a summer at BofA and are now applying again for just GS/MS/JPM.

For spring weeks, it's also highly confounded by the fact that only a small number of people do spring weeks and they tend to be the more dedicated applicants so high have high success rates in general. They are also much more likely to be diversity.

Using common sense tells you that on average someone with a previous internship has better odds than someone without. It is however quality over quantity. I don't see the value-add of doing three IB internships instead of one good one.

How the hell do you even get three IB internships in your very first year as a student? Why are kids these days such massive hardos?
