Feeding ratios

Toast

Does a maintenance feeding  ratio of 1:1:1 vs 1:2:2 or any other ratio make any difference to the starter?  As an example, after doing a bake there's maybe 10g of starter remaining.  I need 227g of starter for another bake. Does adding 110g of water and 110g of flour have any undesirable affect on the starter for the next bake??

It may take a while to get a ripe starter, but there shouldn’t be any undesirable effects once you have a ripe starter. 

Feeding ratios are more or less for how often you want to feed your SD starter assuming you have a strong one to begin with, as all bets are off if you have a new starter that is weak and is not quite ready for prime time. 

Yes. Start with feeding 1:1 and see how long it peaks and if then increase from there until it peaks per your desired feeding/dough making schedule. I feed mine 1:10 at 60% hydration only once a day. Everyone is different so you have to find out what works best for you. Again, if your starter is not ready like I said all bets are off.
