Looks like I will have to go see HCAD in person

Just received this message: "Dear Property Owner: Thank you for signing up for our iSettle™ program. Unfortunately, after reviewing the information we have available, we cannot propose an online settlement for your 2020 protest. Since sales disclosure is not mandatory in Texas, we acknowledge that our market information may not be complete and that you may have evidence unique to your property that may support a reduction in your property’s market value. To be sure you have an adequate opportunity to have it reviewed, we will be setting you up for appointments with one of our appraisers and for a hearing with the Appraisal Review Board. The Appraisal Review Board will set a hearing for your protest and notify you electronically or by mail of the time, date and place of the hearing by standard USPS mail."

Means I will have to go sit in a crowded waiting room and wait to see a panel of people in a small room. Not my first rodeo. The question is, should I go?
