I look at your DB, and this looks like the type of DBs I make. I tend to do engineering, math, science related not business and admin. I have to imagine you are doing some type of analysis on the data, which means this is query intensive. I am assuming comparing runs, getting statistics, etc. I have to imagine this is super hard in this design.
Normalizing this is not as hard as people think and redesigning forms will be so much easier than making this form originally. You will reduce the number of fields and controls by hundreds. I see about 30 controls multiplied by about 12 sims. That becomes 30 not 30 x 12. I am surprised this form did not max out the control limit.
If you are not familiar with doing normalizing UNION query, you need it. You will be able to relatively easily move data into a normal table structure.
If this is something your willing to share, I can assist as needed in normalizing.
