Ah, so unfortunately the delay is only applied to new data coming in. When you start a live session, we only get the current state and new data coming from the F1 feed, so we can't delay back to a point before you started listening to the feed. You also can't "rewind" the session, so any data that has been shown won't be removed, only new data will be added (after the delay you've set).

Currently the delay is designed for a minute or two's worth of delay for a live TV feed, or for replaying old sessions. I don't currently have a good way to support a long delay during a live session, without you starting the app before the session starts, and applying the 25 minute delay immediately so that all the data is queued up to be displayed in 25 minutes time.

oh, thanks for responding! I'll try to start the program before the race starts tomorrow.
