Can you guys slow down the Tactics Trainer clock?

That's pretty funny coming from a kid who lists "International" as his location! 

International track event distances, including the Olympics, are all metric distances, including the 100 meter dash.  So are NCAA college distances in the U.S.  I don't know about high school.  Way back when I was in high school in the 1970's most school districts ran yards distances rather than meters, but they have since switched to metric distances.  There might be some school districts that still run the old distances.

EDITED for clarity.

100 metres = 110 yards

No arguments here-- the refusal of the U.S. to switch is an embarrassment and a financial drain.  And the loss of NASA's 1999 Mars Climate Orbiter because of a metric/english snafu was borderline criminal.

Living right on the Canadian border, I get a mix of both systems.  Canada did it right in the 1970's when they took the plunge and made the switch.

 I certainly agree that it was right to switch in the 1970's. What would happen if the US tried to do it now? Its annoying for us because a lot of our trade is with the US, so we kind use a mixture of both systems.

It would cost too much to change now for the USA would it ? and British hasn't change too.

As far as the OP, I don't agree with Skipgugg. Aging does slow the thinking process IMO. You can switch the tactics trainer to untimed mode, but there is no rating in the untimed mode.

They don't want to get along with the French etc.

 I think the UK uses the metric system for the most part. I think they are still in the process of making it the offical system. I am not certain about this though.

 Money and pride. IMHO

The last real push for metric in the U.S. was in the 1970's at about the same time Canada switched.  Several states started posting highway distances with both systems, and giving temperatures in both systems, along with a few other changes.  But if a push comes from the Federal level, the conspiracy nuts start screaming about world-order influence, businesses start screaming about massive layoffs resulting from their "conversion" expenses, and all sorts of other hysterical scare tactics pop up.  It's political suicide in the U.S. to advocate the metric system.  Bottom line is that most people, regardless of the lack of logic involved, don't want the change, so it doesn't happen.

It's our own fault, but the U.S. is in exactly the same boat.  Anything that we trade with any other country has to involve both systems, so our manufacturers have to use a mixture of systems too.  On the other hand, sometimes it generates more business.  For instance, every household toolbox needs a set of both metric and english wrenches . . . 

109.36 yards, to be more precise.

By the way, I am somewhat in agreement with the OP on the clock and points allowed set-up for TT. If you get it wrong, either instantly or using a lot of time, you are penalized the full amount (perhaps as it should be -- you got it wrong!). However, the score drops very quickly for right answers. A correct answer in average time yields a reduced positive score (the percentage is roughly the equivalent of a "D" when I was in school!!), and a correct answer in double the average time is worth virtually nothing. OTB or live (with a "standard" time control), I'm likely to give a move more than 14 seconds in a critical position, even if my first impression proves to be the correct one. In some of the TT puzzles, 14 seconds is practically a failing grade.

I think adjusting the speed at which credit is reduced might yield fewer quick guesses and, once the rating values of the puzzles have had time to realign, a more accurate measure of one's ability.

It is the official system. But most Brits resist it because they think it's too European and not British enough.

Makes for some fun when you read headlines like "Europrats make buying a pound of potatoes illegal!" because, legally, items should be sold by the kilo.

That level of precision is scientifically invalid because of the number of "significant" digits right of the decimal. The precision you indicate is on the order of magnitude of millionths of a wavelength of visible light. How would you propose to measure it, especially once you've crossed into the realm of the Heisenberg Uncertainty Principle?
