The ratio's are a good way to use as a comparison. I now keep track of the charts from Coinbase. I compare BTC, LTC, and ETH on the Hourly, Day, Week, and Monthly charts. Ethereum is weakest for the week. BTC up 23.62%, LTC up 10.91%, ETH up 2.56%. (All this before the break out).
However, LTC is the weakest and only one of the three negative for the month (-14%). This is why the ratio is out of wack and I am agreeing with you.
Note: Today, I bought some Silver Eagles with some of the profits from the rise. With litecoin going up 13% today and silver going up around 13 cents there is a larger spread of value here.
