Actually what's wrong with new boost?
I think the new boost is good because if u really drive during PHG, u easily earn more than the PHG, meaning u don't actually benefit from the PHG.
Since now the payout is at least 1.2x, your 20% or 25% Uber is covered from the boost. In other way, you will get the 'full fare' amount from rider.
Because the new boost payout (if 1.2x) will be much lower than what you will getting if you hit PHG
Example
Say period 4-8pm, boost 1.2x. You drive 8 trips, but, all trip is short trip, not more than RM5. So, you get RM40 for 4 hours. Then, you compare, say, you hit Tier 1 PHG, which is RM30 per hour. With Tier 1 PHG, you guaranteed RM30 per hour, so, 4 hours, you got RM120. Then, you less 20% Uber commission, you got RM96
So, with this new booast payout, you lost our RM56, which is 58% of what you used to be getting.....so, you think it worth or not? Those aiming for PHG sure dulan lah

, while for me, doesn't matters....
Sorry for so much number analysis here, I think it better I give example with numbers rather than plain bullshit story with no supporting data of what

The only good thing no more guarantee hour is you do not need to keep your acceptance rating high anymore.
You can pick and choose your riders and trips.
