That sounds like a solid plan. Start by cataloguing each step of the plating routine and assign a numeric value to every measurable element—angle, distance from the plate center, time taken for each action, and even the weight of each garnish. Then, calculate the mean and standard deviation for each metric; that will show you where the process is consistent and where it drifts. A simple spreadsheet can track these numbers over time, and a scatter plot will instantly reveal any outliers. Once you have that data set, you can run a regression analysis to see which variables most strongly influence plate symmetry. The results will give you a clear, objective roadmap for tightening the process. Let me know if you need help setting up the template or interpreting the numbers.
