Had a chat with some clubmates with these tops on the LSR on Sunday.
The general opinion was that, we couldn't wear it racing - I've got a club top that allows the AAA race cost reduction, and you have to run in club kit anyways.
I wouldn't wear it training with clubmates as we all know each other's times, there's people both faster and slower than me.
We also discussed that it would paint such a large target on your back were it used for racing or solo training.
On reflection, it's a nice idea, but not for me.
