Lets see, you have 100% chance of hitting a chunk 4/38 and 0% chance of hitting the numbers on 34/38.
Or you divide the wheel into 4 and give each section a missing number to give you about a 1/9 chance of hitting on each section. Very interesting Dr. Jones.
Technically it is probably exactly the same.
The way I would do it is to find the 4 coldest numbers and and not bet those because there could be a defect preventing those numbers from coming up as much.
The 4 coldest numbers in how many spins backwards?
