Market aware offsets combined with parametric order books will be a boon. But market aware offsets will take a bit longer until they are available.
For now we have to make sure that Nu doesn’t lose more money than necessary when keeping the peg while supporting the BTC hedging business.
An offset of above 1% combined with only a few thousand USD value in that range seems to be sufficient to shy professional traders away. Their bots seem to be configured to hunt for higher volume at lower offsets.
I don’t care much about the spread for ALP as this is a different kind of business.
If we can’t reach the ALP targets for the fee we are offering, we need to increase the fee or allow a bigger spread.
As long as we are close to the target, the spread can be as low as possible 
For the Nu funded gateways it’s somewhat different. They aren’t really meant to handle the main trading volume and are designed as line of defence for the peg, that steps in, when ALP fails.
For those who might doubt the effectiveness of that - did you find a lot of alarming messages, paging FLOT members to deposit this or that here or there in the last weeks?
One reason is the relatively stable BTC rate.
Another reason is the buffer the gateways introduced, which can handle some swings without having the liquidity derailed - especially valuable at Poloniex.
To make this buffer created by Nu funded bot funds last as long as possible, the offset beeds to be decent.
And my sell side only gateways are even at above 1%.
Creating arbitrage opportunities by maintaining sell side only gateways with a too small offset would be silly
