Hold on a second! A clarification in this post must be made. There are eleven
(11) people in the picture and eleven (11) people named in the effort.
That means that 11 people completed the ISD build in 1 hour, 2 minutes and 28
seconds not 10. Is this true?
If true, that means this effort had 11 participants. Analyzing the effort I
break the record down into per-person time units and discover the following:
A record of 1 hour 2 minutes and 28 seconds is equivalent to 3748 seconds of
time. Divide 11 builders by 3748 seconds yields 0.0029 builders per seconds
The previous record of 1 hour 9 minutes and 22 seconds is 4162 seconds and
dividing 10 builders by 4162 seconds yields a 0.0024 builders per second
ratio. Clearly, 0.0024 is smaller than 0.0029 and therefore faster than this
attempt.
If we were to factor in this attempt with the builders per second speed
acheived by the BrickFest PDX record, then this group with their 11 person
should have acheived a time of 4583.3 seconds or 1 hour 16 min and 23 seconds
(11 men divided by 0.0024). Obviously, by using the 11th man, the latest
attempt had an unfair 11th man advantage providing for 14 min in additional
speed.
If we examined this using the man hour analysis we see that the BrickFest PDX
attempt was still faster. In the 11 man attempt each person accounted for
340.7 seconds of the overall time (obtained by dividing 3748 seconds by 11
and assumes each person contributed equally). This equates to 5.678 minutes
per man or 0.0946 man hours. The previous record attempt equated to 416.2
seconds per man or 0.1156 man hours.
While this second figure is bigger, realize that the 11 man and the 10 man
groups performed the same task and we must account for the 11th man in the
latest record attempt. If we subtract the 11th man’s contribution, we must
recaculate the record attempt. To do so, I add the 11th man’s time portion to
the overall time acheived by the 11 person group. This time, 340.7 seconds
added to the record of 3748 seconds becomes 4088.7 seconds or 1 hour 8 min
and 8 seconds.
While this time is faster than the BrickFest PDX attempt on the surface, any
good mathmatician knows that you must perform the same function to both sides
of the equals sign, so we must also subtract the 11th man’s contribution from

Really?
Subtracting on one side to make 10 and adding on the other to make 11 is not
doing the same function on both sides. Just the maths pedant in me speaking, but
last I checked, when doing statistical, numerical, any kind of analysis, the
objective is to make all sides fair. therefore, there is one possible option:
a) Find the lowest common denominator of 10 and 11 (in this case, 110) and
multiply the side with 10 people by 10 (Since the number being multiplied is
larger) , and the side with 11 people by 11 (Since the number being multiplied
is smaller). This will give a standard answer that will show clearly the
variation (and if you really must, you can divide these times by 10 each
afterwards to get the times for 10 people)
PDX: 1 hour 9 minutes and 22 seconds
= 4162 seconds
x10 = 41620 (duh, it’s x10 :) )
Lastest record: 1 hour 2 minutes and 28 seconds
= 3748 seconds
x11 = 41228
Now dividing both sides by 10 (thus assuming 10 people on each team) we get
PDX: 4162 seconds
Latest record: 4122.8 seconds
this means PDX result is 1 hour 9 minutes and 22 seconds
and the latest record is 1 hour 8 minutes and 43 seconds (rounded up, though it
should be down)
Top that, calculation-boy!
Now, all of this is actually pointless as pointed out in previous posts, as the
11th man was not actually helping with the building. (Well, one assumes not)
but even if he was, the latest record still stands.

Obviously, the BrickFest PDX record still stands, when you consider the
contribution of the 11th man in this last attempt.
Sorry fellows, I guess we will just have to asterix this 11 man attempt as a
nice try.

Heh, sorry to jump all over you like that Todd, but I could not let that maths
stand.
Just my two 1x1 round plates
Cheers,
