1. free和back圈数算多了。如果连续游6,7圈。好像总会多个半圈或者一圈的。看着这
个分圈计算，好像有的时候一圈split成两圈了。

是不是这个手表不太适合flip turn啊？儿子有可能flip turn还是不标准。turn的时候
手臂有些动作。而且儿子六岁。是不是手短的话就容易算错圈数？
或者是有的当中动作有节奏不稳定就容易算错？
2.butterfly认成了free style。不知道garmin怎么区别的。靠手recover的速度？

3.back stroke总体还好。就第一个length和最后一个length认成了free style。然后
。多了半圈在第四个length（14秒，不知道怎么出来的）。

总体还是很喜欢这个gadget。儿子也很喜欢。如果能够再准确一些就好了。 | i*********5
发帖数: 19210 | 2 Troubleshooting Pool Swim Data
http://www.dcrainmaker.com/2011/10/garmin-forerunner-910xt-in-d
I wanted to briefly talk to this, since I’ve seen a number of folks ask
about accuracy in the pool. Some have had the distance issues where the
unit reports longer than normal. And a few people have issues where it
reports shorter. With that, I wanted to provide some tips based on my using
it for the past 5+ months. During which time, I’ve had it measure
distance in a pool wrong only once – due to having to stop mid-way down the
lane and converse with my lovely wife. Yup, just once. So I figured I’d
share my tricks to accuracy.
The first thing to keep in mind is that the unit measures distance purely on
accelerometer data. That means that it’s measuring what your wrist is
doing, and in particular, changes to direction and acceleration. Thus, you
have to keep in mind that any movement you make while the timer is running
is being analyzed. The watch is constantly thinking “Is this a stroke?”,
“Was that just a new lap?”. Keeping that in mind is critical to accurate
data.
1) When you’re not actively swimming back and forth, pause the timer. I
know that there’s some guidance that says you can just keep it going, but
honestly, that’s wrong. If you’re standing at the wall waiting for your
next set – just pause the timer. That tells the watch to stop looking at
whether or not you should be swimming. And thus, it won’t increment the
distance until you press start.
2) Separate out your laps/sets using the lap button. If my workout calls
for 1000y warm-up, then a 500y build, then a slew of 100’s, I’m going to
press lap between each section. Thus, at the 1000y marker I press lap to
create that set. At the 500y marker, I press lap. And then after each 100y
I press lap. In the case of the 100’s, I’ve got a short rest at the wall
, so I FIRST press stop, then I press lap. If I pressed lap then stop, it
would incorrectly start a new lap that I haven’t started swimming yet.
3) Be strong on your wall push-offs. Because the 910XT is looking for
changes in acceleration, you want to ensure that you push off the wall
strongly. Fast being the key. It doesn’t matter if you do a flip turn or
an open turn (I vary sometimes for fun), it just matters that you do it with
conviction. If you ever-so-slowly do a turn at the wall and make it more
graceful than Ms. Daisy, the unit might never actually detect an
acceleration change, and thus, no new lap.
4) Be aware that passing someone mid-line is an acceleration change: Folks
have reported issues with sudden surges to pass another swimmer mid-way down
a lane being counted as a new lap. This is an area where Garmin could
improve the logic a bit, but my advice here is to try and ‘soften’ the
acceleration/deceleration just a touch to not trigger it. I realize of
course that when it comes time to pass someone mid-lane, the most important
thing is doing it quickly – but just offering some options. Or, do it at
the end of the lane (again, not always possible).
5) Pause when in drills: Because the unit is looking for one of the
recognized stroke types, it will only be accurate when you’re doing one of
those stroke types. So if you’re doing a bunch of drills with three pieces
of swim equipment and look like a fish out of water, it’s best to pause
the timer.
6) It won’t work if your arms aren’t moving: This goes hand in hand with
the above, but if you’re doing kick-only drills, the unit simply won’t
measure that distance. For these, I just pause the unit. The time is
counted in total activity time, but it doesn’t try and incorrectly record
laps (which it will, trust me).
7) Don’t leave the unit running when you go to the bathroom: I only mention
this, because I got an upset e-mail from someone that indicated that the
unit incorrectly added a lap when they went to the bathroom while leaving
the timer running. I really wanted to note that technically they probably
did go 50y round-trip, but decided against it. Again, remember, as your arm
swings, it thinks your swimming. So as you get out of the pool, walk to
the bathroom door, open the door, go to the bathroom, and do it all again in
reverse, it’s prime time for the unit to think you’re swimming. Just
pause, you’ll be happier later. :)
准。

发帖数: 978 | 5 Which button do you press when you do the "Press LAP"? I did not see this
in the manual. It only mentioned press stop.

慢吧。14秒是sprint 25Y？
