You have to understand we are talking about changing convergence as the temperature of the optical block stabilizes over time. It is not how long it takes to become perfectly converged. It never will be perfectly converged. It will just stabilize and then using timing changes to the blue and red grids and scaling tricks which have small negative effects on resolution focus and sharpness to give one the appearance that the unit is converged. It isn't physically converged and and never will be. The issue becomes what you can see from your viewing position. The fact that it is changing over time has nothing to do with the image quality. When it eventually stabilizes it may in fact be better not to use subpixel converge adjustments at all. They converge nothing, They simply hide the misconvergence at a cost of resolution and sharpness. Full pixel rather than subpixel is another issue and has benefit without any real costs to the image. I have written many posts on this subject and do not intend to attempt to explain this again but it is gospel and not questionable. Shifting a line a ful grid line or pixel in who number multiples will reduce any misconvergence to one half pixel or less. If you want to adjust a tenth or two using subpixel, the benefits will outweigh the adverse impacts, 3 to 5 tenths the adverse impacts offset the benefits. Remember subpixel adjustments were added by manufacturers to shut up complaints of misconvergence by customers. Subpixel doesn't fix convergence, it hides misconvergence from your eyes at the cost of resolution and sharpness.
