25.625 x 36 = ~922
4.75 x 189 = ~898
898 / 922 = 97.3% which is virtually impossible, even at 38ppg it's still like 93%.
How are you measuring 1.189 and how do you know it is accurate?
It's not a popularity contest, it's beer!

At that level it has to be calculated unless you have a refractometer that reads that high, I don't yet.
So I calculated the additions I made and added them together initially,  Then checked by measuring the FG by both hydrometer and refractometer and used a calculator.   So yes estimates were involved.

Everything under 1.100 is a 'session' beer

Get yourself a small graduated cylinder, then dilute the wort with an equal amount of water.  Multiply the refractometer reading by 2, and bob's your uncle.  It will be cheaper than buying a high gravity refractometer, \$7.50 from morebeer.
