I'm not an attorney and will not address your attached file specifically. That being said ...
I will say, at least in my area (Tampa Bay) there are plenty of appraisers and therefore plenty of different prices for appraisal services. My base fee is lower than the VA panel fee, but higher than the "volume guarantee" fee I got several years ago. I also have a few clients who know my base fee, however choose to pay well above it! I also quote many properties per year on a case by case basis due to complexity (waterfront, larger GLA, site size, ADU's, etc)
