0. Introduction
In the last post I wondered why anyone would dual mine, since it would be more effective to divert those hashes to the most profitable coin type (SHA256 or scrypt) at the time. I had assumed that dual mining would mean a 50 / 50 split of hashrate. What I didn't realise is that dual mining is essentially extra, and if you can mine bitcoin profitably at 5J / Gh, then you can get some extra coin.
1. New data
All the information I'm using in today's post comes from miaviators excellent post at bitcointalk.org.
For the usual 10 Gridseeds, I'm assuming 3.2 Mhps and 100 W total for scrypt only, 12Ghps and 550 W total for BTC only, and 3 Mhps / 12 Ghps and 600 W for dual mining. All power use includes attached peripherals (eg computer or rpi, USB hub, wifi bridge) and have been rounded up.
Using these data point, the following chart gives a clear indication of the importance of dual mining on devices that can do it.
2. Conclusion
If it is at all profitable to mine bitcoin at 5J / Gh in your area, then you should dual mine. If 5J / Gh becomes unprofitable, or the litecoin exchange rate increases significantly, I'll revisit the question.

I'm terrible at proofreading, so some of these posts may be worth quite a bit to the keen reader.
Exceptions:
- Errors in text repeated across multiple posts: I will only pay for the most recent errors rather every single occurrence.
- Errors in chart texts: Since I can't fix the chart texts (since I don't keep the data that generated them) I can't pay for them. Still, they would be nice to know about!
