Isn't it better to display 100 * (a + W/2) / (a + W + b) instead? This shows the portion of buffer before the window-center. It will show 50% in the first use case and 73% in the second. IMO, showing 98% in the second case sounds misleading, not unlike the current 49%, because it effectively disregards the text inside the window, and thus can lead to skewed estimations when the part inside the window is non-negligible relative to the part that outside.
