My head is doing just fine.
But since you brought it up I am now having to suspect you need a beak but wont/can't admit to it?
Getting challenged on real world grounds and having to think beyond your idealisms and into the expanded realities that the world runs in is tough sometimes.
Just wait until you get your ideas worked over on the real world economic feasibility limitations aspects of it all where ever changing costs of feedstocks, labor, processing, user demographics, special interests limitations/roadblocks and wants and who knows what else all start ripping handfuls out of the profits possibility pie!
Not really. Rather nearly the opposite in fact. In finally admitting that the ranges vary and overlap barely (your best 100% pure end product still doesn't break the lower 1/3 range of raw unprocessed well based Natural gas) you have proved mine (that their is a overlapping range they both share) that I have been going for since the begining. Thanks for keeping up.
BTW in real world applications that bio derived CH4 value of 1011 Vs Natural Gasses value ~950 - 1150 variance is only ~ -6% to + 13% (a range that will not play a major make or break feasibility problem with any typical bulk heating/engine fueling applications) which means that their is a fair chance that any randomly sampled Natural Gas source has about a 2:1 odds of being equal to higher than your pure Methane source.
Plus beyond that, in real world operation conditions, where purity is not so critical and end point costs is, the efforts you will have to put forth to clean your gas up just to meet the lower end average of natural gas will set you back way more given the bulk of your impurities are low to zero value byproducts (water vapor, nitrogen compounds, CO2, H2S, oxygen, Etc) where as raw well gas "witches Brew" has a load of highly valuable secondary gases that in their removal work toward paying for their separation hence the reason that Natural Gas processing plants are highly profitable!
Unlike well gas sources of which many can and do run straight form well to end user, and those that doe get theri secondary compounds processed out (profitably), your bio process is alway going to be totally dependant on a feedstock supply that is either labor and cost intensive to gather process and dispose of or is stuck with being tied to a waste process only feed source (nitch source application).
Plus you will alway be up against the limited value of what your secondary byproducts that come from cleaning you gas has (measurable energy and financial outlay with little return for it just to get your end product up to base level competitive spec).
I think your work has merit on the academic end but I am not seeing a strong power play on the greater implementation end, so far, due to the likely large up front cost to set up plus parasitic secondary efforts and their cost that may be involved, which is what investors are looking at ( I obviously would be any way) when they give you money, that they ultimately want it back and with a preferably good profit for it.
The whole reason they are rich is because they don't buy into blind idealisms that don't pay equitable dividends.
Especially on the real world bigger picture application efficiencies and cost comparisons, like say comparing the typical real world engines (typical mom and pop daily driver vehicles) users to your high cost special purpose built rigs (Tesla roadsters very few will own simply due realistic costs and limited range of applications involved).
One may have way better working efficiency but its cost is way outside of what the average person and end user can afford to work with or cost justify.
We can continue on but at this point with your latest revelations I see no need to. You have pretty much shown what I have been getting at all along, that they in fact partially overlap on energy density, with yours running largely second to common well source Natural Gas on all levels of measure in likely 2 out of 3 instances.
Winning 1 game in three on average energy comparison alone does not make you the superior player. Even less so if you have to put forth a lot more efforts just to play at that level while your competition does not.
