That section of the manual describes the process I used better than I could, so instead of re-inventing the wheel, I cut, pasted, and highlighted. I apologize again to you for not clarifying this.

No, not at all! No worries, and no need to apologize. I understand now. Those instructions might be helpful to others reading the thread, so thanks.

I don't know, actually. Go for it!

Well, since I have a Bunn My Cafe now (MCP high-altitude), I was able to check how much coffee you get per pulse using this machine myself. I'll copy the results I got originally with my OPOD below this post for easy comparison.

Let's start with the 8-oz. drop. The Bunn's tea setting gives you 3.5 pulses at 8 oz., so of course these pulses are longer and less frequent than the OPOD's. Here's the skinny:

3.5 pulses - 7.86 oz. (+0.70)
3 pulses - 7.16 oz. (+2.78)
2 pulses - 4.38 oz. (+2.80)
1 pulse - 1.58 oz.

In the future, I'll be interested in figuring out how many pulses you get for the other drop sizes (from 4 to 12 oz.) and how these "pulse per drop" figures compare to the same data for Bunn's new My Cafe Home.

I don't know if anyone besides me will find this interesting/useful, but here goes!

7 pulses - 8.22 oz. (+1.38)
6 pulses - 6.84 oz. (+1.20)
5 pulses - 5.64 oz. (+1.30)
4 pulses - 4.34 oz. (+1.34)
3 pulses - 3.00 oz. (+1.20)
2 pulses - 1.80 oz. (+1.30)
1 pulse - 0.50 oz.

Edited the title just now to more accurately reflect what this thread's about!

Really? Have a link?

Have a Gen 1 machine. Let me check.

Light, no initial pulse, just straight through.
Medium, one initial pulse then straight through.
Bold, one initial pulse, short pause and four additional pulses.
Tea, one initial pulse, longer pause and four additional pulses.

Well that's news to me. Very interesting. Thanks!

starryeyes wrote:I counted the pulses on the Bunn My Cafe Home. I used a 12g. ogopogo pod and 9 oz of water. I usually use 8 for this but I wanted to see what would happen. I got 9 pulses when using 9 oz. Next time I'll use a 10 g. pod and 7 oz and see. I wonder if it will give me 7 pulses and if it dispenses 1 oz/pulse. My experiment shall continue.

Awesome. That's a big change from the commercial units. Can you taste the difference (if any)?

This is still pretty close to 1-oz. pulses. Not worried about flavor transferring to your non-flavored coffees down the road, or did you get a spare pod drawer?

Back to the issue of "pulses per ounce" with the Bunn My Cafe Home (or MCH), below is a summary of what I found. These data were gathered from water-only brew cycles, but I doubt results would differ if I wasted a bunch of pods to gather them. The (short) designation indicates a partial pulse, i.e. one cut short at the end of the brew cycle. I didn't count the little puff of air you seem to get at the very end as a pulse. What I see is an average pulse of a little under 1.5 oz. that doesn't seem to vary according to total volume of water dispensed. Does this seem about right to those of you who have this new(ish) machine?

(drop size in oz. - # pulses)
4 oz. - 3
5 oz. - 4 (short)
6 oz. - 4
7 oz. - 5 (short)
8 oz. - 6 (short)
9 oz. - 7 (short)
10 oz. - 8 (short)
11 oz. - 8
12 oz. - 9 (short)
13 oz. - 10 (short)
14 oz. - 10
