Assuming afternoon and evening draws use the same equipment, why keep them separate unless perhaps you think the time of a drawing affects the outcome? The equipment doesn't know what time it is, so whether it's two draws a day for n days or 1 draw daily for 2n days the data will consist of 2n samples.
In reality, different draws will use different balls and/or machines, but you won't know ahead of time which ones will be used. The best you can hope for is that using data from all draws and all equipment will provide generalizedresults that can be applied to the unknown balls and machine that are used for a subsequent draw.
