Given that you previously stated $P^{'}$ and $E^{'}$ were the native currency of Polkadot and Ethereum respectively, should those be used here? Or should we just use DOT and ETH throughout?

The mathematical notation was useful for distilling the essence of the algorithm. However I've made it more clear in 495ab69 that DOT and ETH are alternative names.

These rates are obtained off-chain and the total fee might be too low if the rates were wrong and beta not enough to cover the difference, right?
I might add a little note here to highlight the importance of getting the correct exchange rates and the consequence of not having them.
