Memory as in volatile/cache/buffer memory? Okay, I think this was misunderstood. By "on demand", I meant having the ability to view Snicko/Hot Spot for one particular delivery that resets after the lifecycle of the said delivery is complete.
For example: I played and missed one at 2.1 overs. I go and watch the snicko for that delivery. Then I played and missed the next one too. So this time, the snicko would be available for 2.2 only and not 2.1. This would mean at any given time, the data will be available for a single delivery only and not past deliveries.
Yeah basically I don't know haha! It's not they are not allowed to though.
