Now that all the numbers are in, we sat down and did a little math. We took 19 trips to the store, averaging 3.47 gallons per purchase. This worked out to 66 gallons purchased in 105 days, for an average of 0.629 gallons (80.4 ounces) per day.

Let's assume we ate every single meal in this apartment (which is not true). 630 meals in 105 days translates to 13.5 ounces of milk per person per meal.

This is an annual milk consumption of 230 gallons (115 per person).

Put simply, we consumed an average of 3.35 ounces of milk per hour, every hour of the day, for three and a half months straight.

This is equivalent to each us being hooked up to a 50cc per hour IV of milk at all times for those three and a half months!

The slope of the regression line was 0.637, which was not far off from the mean consumption of 0.628 gallons per day. This indicates a very steady rate of consumption, though the y-intercept of 1.29 suggests we slowed down. Here are the numbers:

Purchasing habits:
Mean purchase- 3.47 gallons per trip
Standard deviation- 1.79 gallons

61.1% of purchases were within 1 standard deviation of the mean purchase size, which is surprisingly normal for so few data points.
If you want to check our math, and God help you if you do, the spreadsheets are actually accessible in Google Documents at this link.

This has been considerably more work than ever expected. We hope you enjoyed reading as much as we enjoyed drinking.

Our pace slowed to a crawl of late. I've been busy with exams, projects and end-of-term celebrations, and Jeremy hasn't spent a weekend here in some time.

Even with the anti-climactic tail-off we've still drank a ridiculous amount of milk! We'll do some final stats and a postmortem once I officially move out this weekend.

It's April and we could still refrigerate them outside!

Also, Sanjay was delinquent in his photographic duties regarding gallon 56. Let this serve as his public humiliation.

56 through 404

Since the pace has been picking up lately, we decided it was time to go whole hog and invest in the real deal.
Say hello to Janice! We picked her up at auction today. For some reason a dude was selling her 2-3 months post-partum, so she's in peak production right now. In order to keep up with Janice we're going to have to up our pace to 10-13 gallons a day!

Notes on pace

March was our most prolific month of consumption with 24 gallons purchased (more than 3 quarts of milk per day). This can be attributed to me being around 4 of the 5 weekends and no spring break to thwart our quest.

It was more than twice the number we drank in February (10). This means, with only one month left, we are accelerating toward the finish line.


Whenever Jeremy or I returns home after a milk purchase we summon the other to help lug the milk up the stairs. These are normally joyous occasions of camaraderie, but today the joy was destroyed.

As I approached Jeremy's car, ready to provide assistance, I found him with a sheepish look on his face. "What kind of sad event could be eating into what is normally such a stellar occasion?" I wondered to myself. As I came nearer Jeremy revealed to me the source of his shame. From the back seat of his car he lifted a single gallon of SKIM MILK white coloured water!

As he lifted the gallon into view he ashamedly mumbled something about "being whipped" and maybe something about "the ball and chain," but my horror was so great that I remember little else of his explanation. You'll have to ask him to explain. My outrage is so great that I cannot even bring myself to ask for more detail.

UPDATE: Needless to say, this gallon will not count toward our totals. Neither he nor I will be partaking of this sub-par liquid.

The arrival of Bell's Oberon to store shelves this week may put a dent in our Milk consumption.
