:3) - ''this DIY project may not exactly match that timings.'' - as far as I remember, you confirmed that you do not use 1/300s, so it's correct, too. --[[User:Nocash|Nocash]] 18:12, 8 April 2010 (UTC)
Yes, parts of it are true but very misleading. Because the Mouse/Interface, Real or DIY isn't controlling the sample rate, the CPC is. So both the real and DIY mouse just ensure that there is always data on the buffer, so that when the CPC asks, there's data there to read. How often the buffer data changes, depends completely on whether and how much the user has moved the mouse (in both the real and DIY mouse). If you don't move the mouse the buffer won't change, so the "change rate" on the mouse side of the buffer would be zero. If you move the mouse fast enough, the buffer could theoretically change on every sample read from the CPC. But both the real and the DIY interfaces can easily supply the data much faster than 1/300s so that in both cases the CPC is the limiting factor.
