// Bmsc doesn't send a completion message when it finishes
// the full nonce range, so to avoid being idle we must abort the
// work (by starting a new work item) shortly before it finishes

// Thus we need to estimate 2 things:
// 1) How many hashes were done if the work was aborted
// 2) How high can the timeout be before the Bmsc is idle,
// to minimise the number of work items started
// We set 2) to 'the calculated estimate' - BMSC_READ_REDUCE
// to ensure the estimate ends before idle
//
// The simple calculation used is:
// Tn = Total time in seconds to calculate n hashes
// Hs = seconds per hash
// Xn = number of hashes
// W = code/usb overhead per work
//
// Rough but reasonable estimate:
// Tn = Hs * Xn + W (of the form y = mx + b)
//
// Thus:
// Line of best fit (using least squares)
//
// Hs = (n*Sum(XiTi)-Sum(Xi)*Sum(Ti))/(n*Sum(Xi^2)-Sum(Xi)^2)
// W = Sum(Ti)/n - (Hs*Sum(Xi))/n
//
// N.B. W is less when aborting work since we aren't waiting for the reply
// to be transferred back (BMSC_READ_TIME)
