Man i work over 50h a week and have a normal life outside the game. True, I'm married but no kid yet, so ofc more free time. Also true during RC i sometime take my lunch break faster to play.
When I say top 1000 is a coast , it's because I really think it is compared to top 100. With HS, you easily make 700-1000 points an hour.
5/6 k points is required to reach top 1000 so it' 8-9h of grind max...
But you are still accounting for hot streaks. I don't hot streak during RC. Being a free player I need my RP for RTTC and extra packs.
