Hi,
I have actually written a post on PHG earlier which you can refer to for a deeper understanding.
I can address your issues as follows:-
1) PHG are divided into blocks, typically on a weekday 6am to 10am is considered one block, 11am to 2pm is considered one block, 4pm to 8pm is considered one block.
2) You will need to be in the core service area 70% of the time during a particular block to qualify for the PHG
3) You will need a minimum of 1 trip per block to qualify for PHG i.e. For 6am to 10am, you need to have minimum of 1 ride.
4) You will need to have 0.75 trips for every hour you are online throughout the entire week to qualify for the PHG. i.e. Let's say you were online for 20 hours for the entire week, but you only did 5 trips, you won't qualify for the PHG.
5) Let's say you got RM150 in gross fare from 6am to 10am, you won't qualify for the PHG as the amount that Uber underwrite is only RM30 x 4 = RM 120. If you earn more than that, you won't qualify for it, which is why I said earlier its more of a safety net, not so much an incentive
6) My advice to you is to drive where the rider brings you, and trust the Uber system to find you a rider and keep driving. Aim for a figure you can see in your partner app, and any PHG you receive at the end of the week you consider it as a bonus. It's pretty demotivating if the net figure in your partner app is low and you are depending on the PHG to come in by the end of the week. This is my personal opinion.
Will be happy to address any further questions you have on this.
