ok, sort of

that is... ok, back to the jog/walks, but not really ok cuz it has been too intermittent and passive... still, six laps today is better than no laps today, so ok, sort of... and the tracker software remains enigmatic, but the progress feels mostly like progress, albeit slow, extremely slow...

6 laps... 36:37 total time... 3.55 miles (for the same six laps, i know)... 5.8 mph (for the same 36:xx minutes, i know)... 10:20 average mile pace (yeah, i know, as unreliable as the rest)... max speed 9.8mph (this feels like it might be accurate as i did jog the first lap and picked up the jog a couple of times in other laps)... 557 kcalories... and now, on the the laps... 4:55, 7:02, 6:34, 6:36, 5:46, 5:40... and lap speeds (as unreliable as they are)... 5.9, 4.7, 5.9, 5.2, 6.4, 7.0... so somehow the speed for the fifth lap was much slower than the speed for the sixth lap when the times were virtually the same and the speed for the first lap when the time was dramatically faster was slower than either the fifth or the sixth... right... alas, i wish the numbers were accurate cuz, as you know, i love numbers... and stats... mile times were 11:25, 10:29, 10:12, and 4:35 for the final .55 mile (remembering last time we just reached 3.07 miles for the same six laps)... meanwhile, the discrepancy in distance shows the flaw in this software... for each lap: .49, .54, .65, .58, .61, .67... so how does this software measure the same lap with such drastic inaccuracy?... i am sure the manufacturer would have some pseudo-scientific response, but as they say on sports center, come on man...

and last time we recorded 5.2mph yet completed the 6 laps in 35:37 while today we recorded 5.8mph completing the same 6 laps in a full minute slower time... cha cha cha... i do see, looking at the map, one flaw that appears to be causing the discrepancies in distance and that is the tracker seems to be over-reading (for lack of a better term) one or two step variations along the same path and adding considerable distance to the lap distance because of that... the path track has me crossing streets and going through buildings (impossible) way off the path i walk/jog on some laps so the gps sensitivity and accuracy is way off... i suppose this sort of tracker might be more helpful on a trail run, but it shows serious flaws and inaccuracies on a lap run which would lead me to question the accuracy of distance (and all other stats except the actual time) of any run tracked with this software... unfortunately the other software i've tried is no different and shows the same gps variations, flaws, and inaccuracies... so we live with what we've got and the bottom line is the lap times and the overall time and the physical assessment by my own senses and feeling is what matters when comparing progress...

kilometers, aye?... 5.72 km... 9l3 km/h... 6:25 mim/km... 15.7 max km/h... and the laps... 9.6, 7.6, 9.4, 8.4, 10.2, 11.2... and per km... 6:34, 6:42, 7:04, 6:45, 5:58 and 3.37 for the final .72 km... the distance per lap discrepancy, as expected, is similar to miles... .79, .89, 1.04, .93, .98, and 1.09... baffling...

still, it turns me on to know and feel that i've gone out and done this once again... not dead yet...

If people had visible signs or meters that told something about them, what would you want it to tell you?

dumb poll (above), smart responders

all the previous poll votes were somehow erased, so, nevermind... ironically or coincidentally or whatever, the results were very close in practical numbers to the results above shown with just three votes, if you understand the mathematics behind that extrapolative reasoning... i will probably remove the poll at some point... it is a ridiculously useless feature...

SEARCH ME

the thing is, with my tendency to babble and meander and whine and allow distraction to take the lead more often than not, even in this blog that sort of meant to merge brevity with focus like some bloggers do, searching for key words does not always lead to specific information about the subject of that key word... but... here is a start at an easy way to search for key words in this blog... use the search box at the top of the blog to search for words not listed here... if ya wanna, that is... and feel free to suggest words to add to this search shortcut section... click on the words below :)
