The P-5 and G-5 do not make sense. They refer to the G-5 as Group of 5. Do they refer to the P-5 as Power of 5? That doesn't make sense. Who is responsible for the P-5 and G-5 terms? A more descriptive term would have been the Rich-5 and the Poor-5. Or, switch the letters, G-5=Greedy 5 and P-5=Poor 5.
