The MC form itself can be misleading (in my opinion) since "increasing/decreasing" is describing an action that suggests future activity, yet as appraisers we are trained to analyze past activity and report as it relates to the current conditions. For example in my commentary I never state "increasing" or "decreasing" but rather increased, decreased, or has risen/declined over a specified period.
Also the MC form has a median for the first six months in one column and then changes to the medians for the next two-three month periods. WTF is that about? I simply can't rely on that without doing my own prior year analysis which I examine in the same period format, whether it is on a monthly or quarterly basis. So that apples-to-oranges grouping plus the future implications of the wording on those check boxes does not make me sad thinking they are considering retiring it. Maybe go to four columns representing the four quarters of the prior year? Would that confuse the intended user? Perhaps they don't think that sales over 6 months are important, so just group that data together and call it a day.
Overall the current MC form is better than no market conditions form but it could be improved rather than retired.
