is the "Expected time to earn reward" thing in the wallet accurate at all?
I think it's about right, but it assumes that blocks will continue to be found at the rate they have recently been found I think. The network rate has been pretty stable recently, so that's a reasonable assumption.
Edit: I looked into it and did some experimentation. It doesn't look at the recent history at all. It just looks at the weight (age times size) of your outputs and the current network difficulty, and calculates the expected time from that.
I think it's accurate.
Note: the "expected time" it shows is based on the current weight of your outputs. As they get older, the estimate will reduce significantly. My 5 CLAM, 1 CLAM-day output which has an "expected time" of 264 days right now will have a weight of 6 CLAM-days this time tomorrow, and so will have an expected time to stake of 6 times less than 264 days, or around 44 days. 24 hours after that, it will have a weight of 11 CLAM-days, and an expected time to stake of 264/11 = 24 days. (Assuming the network difficulty doesn't change, and also assuming it doesn't get lucky and stake before then, which it probably won't, but could).
