Based on the following 5 gal recipe: https://byo.com/recipe/pilsner-urquell-clone/
"The traditional Pilsner Urquell utilizes an undermodified Pilsner malt that is malted by the brewery. The mash is subsequently triple decocted to help break down the protein matrix that is still present in the undermodified malts. For three reasons we have decided to change up the classic recipe. First homebrewers don’t often have access to undermodified Pilsner malts these days. Second, a triple decoction means a long and rigorous brew day for the brewer. Finally adding in a protein rest could be detrimental to the beer’s body and head retention. So we’ve simplified the mash procedure and added some malts to help adjust the color and add a slight toasted character that the triple decoction should otherwise add to the beer’s profile. Mash grains with 15 qts. (14.2 L) soft water at 142 °F (61 °C) and hold for 30 minutes. Perform a decoction, pull 1/3 thick portion of the mash (~1.5 gallons/5.7 L) and bringing to a boil. Boil for 15 minutes being sure not to scorch the grain mix. Stir the decocted portion back into the main mash. The main mash should now settle at 155 °F (68 °C). Hold for a 30 minute rest. Mash out, vorlauf, and then sparge at 170 °F (77 °C) to collect enough wort to result in 5 gallons (19 L) after a 90-minute boil. Boil 90 minutes, adding hops at times indicated. Cool, aerate, and pitch yeast. Ferment at 50 °F (10 °C) until signs of fermentation have slowed considerably. Some diacetyl is noted in Pilsner Urqell, but if there is a strong diacetyl presence at this point, 2-4 days at 65 °F (18 °C) is advised. Rack to secondary and lager for 4-6 weeks at 40 °F (4 °C). After lagering is complete, bottle or keg as usual."

2.Perform a decoction, pull 1/3 thick portion of the mash (~3 gallons) and bringing to a boil. Boil for 15 minutes being sure not to scorch the grain mix. Stir the decocted portion back into the main mash.
3.The main mash should now settle at 155 °F (68 °C). Hold for a 30 minute rest.
4.Mash out, vorlauf, and then sparge at 170 °F (77 °C) to collect enough wort to result in 10 gallons after a 90-minute boil (target 13 gal starting wort).
