From Gabriel:

One really good observation I had is how to puncture the septum. Normally comes with 7 bubbles. It is to my experience so far that following a systematic puncturing cycle works best as for avoiding gas leakage due to pressure from headspace. I had dog food and WAS in my bottles and the volume on the first days was massive! I did the mistake to do the puncture on the same bubble and I could hear the gas coming out from the previous one. I will send you soon my file with all my observations. Have some videos and pictures too. Also the needle should be changed every 20 punctures in average. The syringe also is a factor. With the screw tip is the best and even better when using at least a 120ml one.

From @koechl , around dev of 304DE v2.2/2.3

One last issue. Is it possible to flip the orientation of figure 2 so that it get bigger by covering the entire page (but in landscape format)? As I/we recommend to possible print it and post it somewhere, it would be useful to have it in a better resolution. Or we add a link from where the high resolution picture can be downloaded from. If the latter, we should probably also add some additional information on it that everybody knows, where this figure originate from (“Figure 2 of Doc 304 …”). What do you think?
