Its not really "live" commentary? I'm getting it about 2 minutes behind? Or is it just me.
All 'live' commentaries have a lag. If you are watching a game on Sky Sports/BT Sport/BBC/ITV etc then what you are watching takes time to transmit, typically 20-30 seconds.
When we were 'live' on BT Sport last season against Solihull, I had the BT Sport programme on my laptop at the top of the main stand & it was about 30 seconds behind throughout the programme, which was very helpful for our commentary.
It was the same at Old Trafford when I did commentaries at a couple of FA Youth Cup games earlier this year. Each media position has a TV monitor, which is about 20-30 seconds behind the action on the pitch.
I check RadioAlty at the start of the broadcast & several times during it. The delay is normally about 20-30 seconds, which is what it was consistently for me yesterday.
In some instances, the delay can be longer & I assume that this is down to the specific internet connection.
