But are my numbers any good? one week with 100 coins didnt stake any. I have 23 payments mostly small ones and 3 huge 50 coins. Or must i send it all to new address as one input?
Yeah, sorry at the moment you only have three inputs- the 50 coins. At the current difficulty, it's estimated that you'll have a 50% chance of finding a block with 50 coins as the input in 8 days, or a 97% chance in 19 days. However, if you combine them all into a single input of ~200 coins, you'll have a 50% chance of finding a block in 4 days, or a 97% chance in 9 days.
