Does virgin media use interleaving?

Does virgin media use any kind of error correction during first 10 day  of activation?

The 10 day training period is only found on Openreach ADSL & VDSL systems over phone lines.
Expect a VM connection to work at full speed at all times.

Check the service speed to the VM Hub + the speed of your device via :

Once the test begins click on: Run full test to see all the stats.

It uses error correction to correct packets where it can (RS). No training like ADSL/VDSL lines.

What you will notice, and it varies by area as some better than others when it comes to HFC network (that's the network with coax at the end into the house), is that the response time is far slower on VM HFC network than native FTTP due to the way DocSIS works. It does add some latency and things not as snappy as on native FTTP where ping times can be 4-8ms and VM's best is around 12ms and averages around 18-22ms for most areas where over utilisation is not an issue. It's noticeable if you've used both types of network, but doesn't cause issues as still relatively good.

So this helps improve the line over time, having the error packets corrected it should help improve gaming performance yes? as long as the hub stays connected 24/7?

They already told you NO.

VM not using ancient telephone wire with limited bandwidth so doesn't suffer from noise easily like BT's cable for ADSL and VDSL (FTTC) does. Noise on VM's network (HFC aka coaxial) is usually a specific issue as significant to disrupt signal on shielded coax and you usually find this affects SNR. They do however user reed solomon error correction. It has no training period like ADSL and VDSL because it's simply not required. VM do not band your line into speed profiles either.

When you get your Hub, look at the Router stats.  The two columns for correction stats are PreRS and PostRS.  The PreRS are the corrected errors and that's fine.  However the PostRS stats are the ones to worry about.  These are data packets that were NOT corrected, but rejected.  Those packets will need to be sent again, causing delays.  In other words, PostRS errors are bad  🙂

As for gaming, stick to ADSL/VDSL/FTTP connections as the latency is usually lower.  VM have recently been installing FTTP in some areas, but most of VM is still the legacy co-ax.
