Which Claim Survives?

Island A covers twice the area of island B, so customers in A are more varied than customers in B.

Island C sits far from every other island, so C's customers are the most unusual group in the data.

Customers 17 and 240 landed in the same island at all three perplexities, so they are probably similar in the original 40 columns.

Next month we can pass the new customers through the same fitted t-SNE to see which island each one joins.
