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.

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.

Bought my ATC refractometer for \$20 online. Works great and saves time.

To the OP subject, when I fly sparse in my 10g round igloo cooler, I just leave about 1-2 inches of liquid on top of the mash and then put a chunk of silicone hose from the HLT around the perimeter about 3/4 of a turn sitting right on the grain.  This is injecting tangentially (and horizontally) from the HLT.  When it is running, the liquid has a slow rotation to it as the sparge water comes in.  No manifolds or arms or whatever, just 4' of 1/2 inch hose.

Sometimes I just run all the sparge water into the cooler at once after the liquid has drained to the level of the grain bed.  That way I don't worry about rates, but it could end up compressing the mash I suppose ( not that it has ever happened to me).

Risk of failure should be no deterrent to trying.

This thread is so old it has a crush on its first grade teacher.

Hey, some first grade teachers have it going on!

I know this is an old thread, but I thought I would post what I do. I use a loc-line that I can adjust to keep just below the water surface. It works very well.DSC_4978 by The Gustos, on Flickr
