Digital A/F Gauge Question

[n0va91TSI]

I was thinking about getting a digtal numeric lcd style A/F gauge

I hear that A/F rations change constantly and I was thinking the digits may change so fast it would be hard to read.

Anyone have this style gauge. Is it hard to read due to contant number change?

No, the numbers only jump around in closed loop
but at WOT its easy to read, the numbers may change once in every 1-2 seconds.
