Hmm. This is very off-topic here but I couldn't ignore this. Did anybody really measure this or did you just guess a random number?
Sure, wireless has *some* "inherent" lag but it's merely a few ms for the best (and most expensive) wireless PC "gamer" mouses (it might fluctuate a bit with high radio interference and such but remains pretty low at all times, really just mere 1-2 ms on average and may be double of that at noise peaks...). And I recall some cheaper wireless mouses scoring around 20-30 ms but I can't remember seeing such high numbers (~80ms) anywhere before.
For comparison, I measure 1-2 ms ping times between my outdoor WiFi devices spanning a few kilometers (and that just plain standard 802.11 "N" protocol, not even the proprietary polling-modes which optionally ignore CSMA --> I think Razer and Logitech does something like that for these mouses, similar to what you get with Mikrotik's N-streme / NV2 or Cisco's similar custom stuff... the radios are tuned to shout between themself, ignoring everything around them and in case of these mouses, optimized for low latency rather than throughput...).
I just laugh at those people but some will tell you that even that ~2 ms should be avoided at all costs, suggesting you should sacrifice the comfort of having no "anchored chains" attached to the brick you try tossing around (e.g. plug in your Ouroboros / Mamba or G900 / G903 for gaming to cut down that few ms). But I agree 20+ ms could start being a problem.
So, I find it a little hard to believe a dedicated gaming hardware clocks in around 80 ms. That sounds crazy. Not even a dirt cheap general purpose bluetooth mouse should be as high as that and we talk about a relatively solid-built, purpose-designed controller solely used for gaming...
Either ways, my main point is, anything above a few ms is not inherent to the wireless radios (unless they are crazy stupid with them) but other parts in the design (like the interfaces these radios are attached or the firmware which controls the whole thing...).
