Tougher Than An Atom

Today’s distance (in meters) was tougher than any atom, because atoms can be split but today’s distance could not be split because is was a prime number, 5,023. You can try to split a prime number into factors other than itself and unity by dividing it with any and every integer less than the prime number and you will not be able to split it. Primes are absolutely indivisible, unlike atoms, any of which can be split if they collide with another particle which has sufficient energy.

So today’s session was done in one non-split RowPro session. It was not split, primarily* for the reason that RowPro 5 for the Mac has a bug which always shows itself if the total distance of a session cannot be divided into splits which are each and every one equal to each of the other split distances.

I don’t know why, but looking at some of the properties of the numbers chosen for the set distance of a rowing session adds a tiny but nonetheless helpful amount of motivation to do the rowing.

The session was recorded and can be viewed for the purpose of rowing-along with it, if desired, at this link:

Four Oh Two Two

That was today’s distance: 4,022 meters.

A Little Dab of Rowing Did It

Today’s rowing was 3,021 meters. Heart rate sputtered a bit and tried to get irregular but eventually gave up that tendency at about halfway through the distance and then stayed smooth and regular for the remainder.

30 Minutes Plus a Bit More

Today’s indoor rowing goal was derived by referring to the time and distance rowed yesterday by one of my training partners. She rowed for a little over 20 minutes, so I converted her total session time to seconds and divided those by the average pace in time per 500 meters of my most recent session. Then I multiplied the resulting number by 500 meters which resulted in a distance of 4,593 meters. That was a bit less than I’d like to row today. I wanted to row at least 5K, so I added her total distance rowed during her 20 minute+ session to 4,593 meters and that resulted in 6,687 meters, which was today’s preset distance.

5019 Meters with Normal Heart Rate

Today’s session was a bit shorter than yesterday’s but it was a lot more fun because heart rate returned to normal, all of its systems were “Go” and behaved A-OK, to borrow a little astronaut lingo.

The above YouTube video is placed at the top of this page simply because of it’s title, “All Systems Go”. This rowing session was NOT a 200,000 Watt effort like what Donna Summers claims her systems are capable of. 🙂

An Undivided Prime

Today’s rowing session was a set distance of 5,519 meters. That’s a prime number, so I didn’t let RowPro 5 for the Mac try to divide it into splits, since it still has a bug which miscalculates results for the final split when it is not the same size as all the other splits.

Today’s session is not categorized as “Fun workout” because my heart was acting up, beating way too fast in relation to the effort expended rowing and that was not fun.

Rounded Down To Avoid A Prime

Finish screen for today’s 1,278 seconds.

Today’s indoor rowing session was 1,278 seconds, to approximately match the time one of my training partners rowed yesterday. She rowed 1,278.4 seconds and I was going to round it up to 1,279 but that number is a prime, which cannot be subdivided into any number of equal splits.

So, I rounded the time down to the nearest second and divided 1,278 seconds into 18 splits.

5,064 Meters

Today’s indoor rowing session was interrupted once, briefly but otherwise it was a relatively constant effort session. The last part tapered off as a sort of warm down.

A Happy Number Session Time

AE-May-14th-2018-31min-40sec-finish — Finish screen for today’s 1,900 second long session.

Today’s indoor rowing session was chosen to be equal in time to that of one of my training partner’s whose time yesterday was 31:40.

To decide on how many splits to have RowPro make of today’s session, I found the factors of the total time in seconds, which was 1,900 seconds. The number 1,900 is divisible by 19, so the session was divided into 19 splits.

While looking at the information available related to the number 1,900 I noticed that it is classified as a “happy number”. The story or stories behind the choice of that name for the particular properties of that number must be an interesting one, but I haven’t found it yet. Happy numbers are the subject of their own little happy field of mathematics. You can look it up, if you want to learn more about it and I will stop talking about it with the period after this sentence.

RowPro 5 for the Mac behaved happily and displayed none of its programming bugs during this session.

Avoiding A Prime Number

AD-May-13th-2018-37min-52sec-finish — Finish screen for today’s 2,272 seconds of rowing.

Today’s indoor rowing session was a set time of 37 minutes and 52 seconds. That’s because one of my “training partners” had rowed earlier, in the “just row” mode and because her session lasted 37:52.4 I thought I would use that as today’s goal, to match that time and do a fraction of a second more, making it 37:53 for my session.

Heart rate tried to be irregular during the first 1/3 of the time but then smoothed out for the remainder.

But when I calculated the number of seconds in 37 minutes 53 seconds, it came out to be 2,273 seconds. That was a problem, because I wanted a total time, in seconds, which could be divided by some integer greater than 1 and less than or equal to 30, which is the possible range for the number of splits that RowPro can make for a rowing session. I wanted to make each split the same as each of the other splits because otherwise RowPro 5 for the Mac always has some calculation errors with the last, unequal “remainder” split.

2,273 is a Prime Number, so it is not divisible by any integer greater than 1.

So, instead of rounding the time up to 37:53, I rounded it down to 37:52, which amounted to 2,272 seconds, which is divisible by several integers in the range from 2 to 30.

Nonetheless, RowPro managed to activate a different glitch and do some miscalculating for one of the splits anyway, the sixth split. I thought that the 6th split was the most appropriate split in which RowPro would manifest a programming error… Not that it matters in the grand scheme of things, but RowPro didn’t even record the correct amount of time for the 6th split. The erroneous numbers in the record of the 6th split are in the columns for Time, Meters and Avg DPS.

The main “bottom line” numbers, the grand totals, are correct and match what the PM-3 recorded on the rowing machine.
