This is a typical result of creating a corridor with a much smaller interval to get a more precise solution. One suggestion is to utilize the Corridor design stages to process the information versus the final output once design is complete. You can set the interval of the corridor to a value and use the Corridor Design Stage 'Template Drop Intervals' to make the corridor easier to process as you are working with the design. Then set the design stage to a final stage with the drop interval or a smaller template drop multiplier.
Or you can unlock the corridor so it doesn't process with every change until you process the corridor or turn the rules back on so it can process.
