So, i'm using org mode to keep track of my workouts on a rowing machine and
need help with 3 questions to allow me to finish off my table.
The questions are based on the provided table, which is what I have so far.
1: in @4$4 and @4$7
i'm using vmean on a column of HMS values, how do I floor or round to the
nearest second, so I don't get fractions of seconds in my output?
$4=0@ 16' 6.333
to
$4=0@ 16' 6
2: i'm lazy and i don't want to type in the split time since I can derive
it from the Watts column.
pace(or 500m split time) from watts formula - 3rd root(2.8/watts)
so
if W = 66 then pace= 3rdRt(2.8/66) = 0.3487 * 500 = 174 seconds = 0@ 2' 54
so
if $11 = 66, whats the best way to put $7 = 0@ 2' 54?
does this call for a lisp function where the output is a text string, or is
there an easier/TBLFM way?
3:
the $1 column of my table is just an i++ value, 1, 2, 3 ... n where n is
the number of rows between the 2nd and 3rd hline.
is there a function I can call to tell me how many rows are in that part of
my table, or, if I want to be able to refer
to a variable which is the number of rows in my table, do I have to keep
track of it manually like this?
so what I want to be able to do is the following, without having to use a
count up column.
@7$2 = Total(3), where 3 is the number of rows between the 2nd and 3rd
hline
Thanks so much, Ryan Moszynski
