No. Lime raises the pH. Gypsum supplies calcium without altering the pH.

If you had a soil test report in hand we could get specific. But a decent rule of thumb is 100 lbs/1000 sf.

If I wanted to raise my Ca level from 2000ppm to 3000ppm in a 3000sf patch how much gypsum would I need? What is the mathematical formula used or is there more to it.

1000 PPM Increase = about 2700 lbs Calcium (as an element) per acre foot of soil. Gypsum is 21-23% Calcium by weight. It doesn't take a rocket scientist to see where this is going. 13,500 lbs of Gypsum per acre (310 lbs/1000 sf) is NOT advisable.
We cannot "fix" a soil test report without causing grave injury to the soil & checkbook.
It is not practical to "feed the soil test" when all we're trying to do is grow better pumpkins. That said, if you are diligent & make regulat annual applications, you can expect your soil test reports to keep improving over time without harming the soil or going bankrupt in the quest.
100 lbs/1000 per year is good provided you soil test a couple months later to be sure we aren't knocking other elements out of balance.

use foliar and drenches of soluable Ca to keep it available to the roots and leaves when it needs it.
