MPC resets the tier points once you reach a new tier, so if you want to become GO in one year, you’ll need 20+300+600=920 points. This makes tier point run difficult if you are new to MPC

Another point that makes MPC tier point run less attractive, is that MPC does not have soft landing, so basically you can go for GO for one year, then green the second year if you didn’t go for another run.
But for BAEC, you can be gold for 2 years, then silver 1 year and bronze, so 4 years status in 1-2 runs.

Anyways, the design of MPC sort of prevents you from having tier point runs. The difference between tier points earned in short haul and long haul isn’t that great compared to BAEC. In BAEC, a simple HK-Europe on QR can almost get you to Silver if you meet the 4 sector requirement. For MPC, the same run gives you only 210 club points. That’s because for BAEC, any sector >2000miles in J gives you 140 tier points. Some “short haul” Europe trips can already do that.

I’m not an expert in MPC runs, but surely BAEC tier point runs are much easier.
