I bought a high power buffalo router a few years ago when I lived in a small condo with many neighbours who also had wireless. I found that I got the best connection rates when I turned the power way down.
Now that I'm in a substantially larger house with only 1 or 2 other networks in range, I get the best performance and coverage across my house when it's turned all the way up.
On a 500km tip, I can knock an hour off my travel time if I go 120 vs 100.

Unfortunately, as you mentioned, many destinations to or from Canada require stops in the US because that's where most of the North American air hubs are (Europe is OK, but try getting to Central or South America from Canada without landing in Texas first)
The reason we use base 10 is b/c we have 10 fingers. If we had 13 fingers, we'd operate in base 13 natively (hmmm.... there's a good thought experiment... what would be some outcomes of operating in a prime base?).
And your comparison is bad.
Quick, what's 125234380034 in base 12 multiplied by 12

You scratch my tape, and I'll scratch yours.
