one other thing I haven't been able to figure out... do we know what a "block" is? Is one block equal to one plot? Or do a series of your plots constitute one block?
I'm imagining that you have 629 blocks, right now doing nothing but sitting there waiting to be picked by the lotto, right? So you win a block and now one (or more) of your plots are being utilized by the blockchain, is that an accurate understanding?
Plots are essentially lottery tickets that are used to validate transactions contained in the blocks. Every 10 seconds a new challenge is sent out looking for a specific combination contained in the plots. Each plot only has a 1 in 512 chance of passing a filter which is used to minimize the number of disk reads required. If one or more of the plots passed filter it moves on for a chance at generating a proof and winning the block. Other than generating proofs for blocks, plots are not utilized by the network.
