During Oman I've fallen from about 13th to 115th on the overall and 1st to 13th on the Rest of World league. Though not without some cause.
There are some changes happening at work and I have been offered my same job in Perth (we are currently in Melbourne) during the last couple of weeks - lots of stress and not a lot of sleep, and then last week we went to Perth to check it out (schools and locations). Normally I have a routine of research and selection on the train (over 30 min each way). I can see how well I do without getting the chance to think about it.
