Why Binance giving more Apr in fixable staking (saving) than locked staking?

[el kaka22]

The idea is that flexible could have a higher reward for now, and lower later on, but fixed price will always be fixed and will always give a return based on that. I personally do not stake there, but if I were then I would pick a fixed compound one which would allow me to grow bigger for many years, whereas flexible would be on and off which would create a bit of a trouble.

Plus, the benefits of fixed is that it would be terrible for you if you leave, hence you decide to keep it in there longer than what you would do with a normal one and I would be definitely taking it out ifi t was flexible, whereas I would force myself to keep it if it was a fixed one.

Flexible staking is one that I can withdraw whenever I want, and locked staking is one that is locked for a certain period of time to earn interest.(USDT,BUSD)
Now my question is, is there any risk in flexible staking?  
Flexible staking is also a benefit for us, then why are they giving more APR on it?

I think you didn’t notice that Binance Flexible Staking has tier based system which only allows certain amount of money in able to benefits on high APY. I post the example below for BUSD Tier Rate.

Tier 1:  0-2000BUSD ; 8% Apy
Tier 2: 2000-20000BUSD ; 0.8% Apy

The greater your capital means you will have less APR on flexible staking while lock staking doesn’t have this kind of limitation. Flexible taking is good if you are using only small capital that is not greater on the first Tier to enjoy the highest APY.

Is APR different for each person? Here  they are showing 20% APR on USDT, BUSD!Here Under below 200$ they are giving 20% and 200<2000 the APR rate is 10% and then over 2000usdt they are giving 0.30% , I am really confused, How does Binance do management their APR system, does it vary from time to time?
