You subtracted one percentage (the amount of the minimal raise, or 1.5%, or about $900) from a different percentage (5%, your asserted medical insurance contribution annual increase) and netted them. That's not correct.
What you're asserting is that your medical insurance contributions increased by $3,000 or so each year, when they clearly did not. That would mean that you now contribute about $15k to $18k each year toward your medical insurance. And since you don't, it demonstrates your lack of proficiency with percentages.
Yes, your medical insurance may have increased by 5% a year, but that 5% is on the very small initial contribution. Your paltry annual 1.5% raise was applied to your total hourly wages (which I estimated to be about $60k in 2003 after the concessions were imposed).
To answer your initial question, there is someone who has compiled everything you lost - contact Bob Owens. I often disagree with him, but he doesn't make such extreme computational errors.
