Makes me wonder how hard they worked those 4 years, or perhaps just that last year they didn't necessarily care to be kept on afterward.

If they were there four years without being let go, the company was clearly fine with the performance.

Makes me wonder about how their investment in effort has carried out over that time. I'm sorry, but X shares over Y time with additional investments of A, B or C, usually means X means a lot less (percentage-wise) for a continuation of effort.
