would also give "Best Practices" if 'x' would have an intention revealing name like 'playerAdvantage' so that it does not need mental mapping.

thanks, now that sentence makes sense!

consecutive strings : follow one after another without an interruption

Those two abigails are not next to each other, are they?

I don't get it: the second example contains the string "abigail" twice, so the longest consec should be "abigailabigal" since the "abigail" Strings are the longest in the array. Instead, "abigailtheta" is expected. The description doesnt tell me anything what the policy is for multiple occurances in the array.
