Excellent guide!!
However, since it is now already post-fork. It is very likely people have different ETC and ETH amounts in their wallet (just like myself). It is better to have a reminder to people when splitting ETC and ETH.

For example, if Peter has 100 ETH and 99 ETC in his wallet.
Check ETH amount with http://etherscan.io/
Check ETC amount with http://gastracker.io/
Split only 98.99 ETH/ETC to avoid any potential error due to insufficient fund in ETC, taking into account of transaction fee.
