I don’t know much about sprouted rice. Most sprouted rice links I found refer to sprouted short grain brown rice. I can’t find a glycemic index value. In these cases, I would play it safe and use a conservative GI of 60 (even though it might be higher given it’s short grain).
According to these nutritional facts: http://www.lundberg.com/product/organic-sprouted-short-grain-brown-rice/, 1/4 cup dry rice has 33 grams total carbs and 3 grams of fiber. Using the FP calculator (https://digestivehealthinstitute.org/fp-calculator/) I get an FP of 15 grams.
For the unsprouted rice milk (http://www.tastethedream.com/products/product/1467/202.php), there are 23 grams total carbs and no fiber per cup for an FP of 11 grams.
