What is the starting dose of Sinemet (carbidopa and levodopa) per day for Parkinsons?

Typical- Misnomer... Quite honestly, as a neurologist I've found LESS AND LESS TYPICAL starting doses of any of the anit-parkinsonian medications as I get farther into my career. Oh, sure there are textbook numbers but when the actual DIAGNOSIS of PD cannot be firmly made at times for years after presentation should there really be such as a thing as a TYPICAL starting dose of Sinemet (carbidopa and levodopa)? Commonly seen is 25/100 3x/day.
