I get it. I gave my opinion, based on what I have learned through reading and my experiences. No one really NEEDS a supplement unless it is addressing a deficiency, then it’s a need. Supplements like these are for those trying to maximize nutrient timing to improve performance and recovery. These are for not for the average gym goer. My thinking 30 grams of carbs as a starting point was not just random:

Research that has no dietary protocol
Research that has no exercise protocol
Research that has no control group
Research that doesn't specify what type of training the trainees were doing. For all we know they could be training at a 5-6 RPE.
When you don't have any consistent variables in your research its hard to draw a conclusion based off a lack of evidence. Anyone can workout 30-60 minutes or 1-2 hours . There is a vast difference when you factor in intense training, moderate training, the average joe training, endurnace based training. This is where specific protocol's, dietary protocol's, trianing techniques all play a factor on what is needed to perform at an optimal level, and what is needed to train like an average joe who goes through the motions.
Are these people training in a fed state?
Are they training in a fasted state?
Folks who train fasted and then throw in intra-workout carbs will immediately feel a drastic differnce, those who are fed may not even see a change in performance, recovery, or endurnace since they are still having stored glycogen from a pre-workout meal.
The outlined article is very cut and dry with no specifics. To take anything off that article is not really proving much merit to anything in regards to carbohydrates and their benefits. I can take any chump off the street who eats 1 time a day in a deficit and then throw in 50g of carbs intra-workout, of course, he will train harder

you can take someone who is well fed (2-3 meals prior to training, a large carbohydrate dose pre-workout, and then train with or without carbs) This would be far more specific and understanding to the current debate at hand. When there is no outline for what you are researching there is no consistent variables to gauage and feedback or progress.
If you are consuming enough carbs throughout the day to replenish glycogen levels, then you will likely not benefit from consuming carbohydrates during your workout.
Some examples:
If you are someone who must train upon waking and cannot perform optimally on a full stomach, you may experience a boost in performance by drinking a fast digesting carbohydrate + BCAA shake throughout your workout.
-- or --
You may also benefit from intra-workout carbohydrate consumption if your training sessions are very high in volume, intensity, and length. A high level Crossfit athlete may fall into this category.
-- or --
Finally, if you are an endurance athlete that exercises for 90 minutes or longer then you may also benefit from intraworkout carbohydrate.
The most important factor in your nutrition is total daily calories and macronutrients. Focus on consistently hitting your macronutrient ranges; this is your bread and butter. Once you are able to be consistent with this, then you can begin to think about nutrient timing. P
lacing your carbohydrates pre and post training session is generally a good idea; this is when your body is most sensitive to them and when they can be utilized best. However, do not go over your daily calories and macros to have a pack of Sour Patch Kids around your training session. As with most things, perfect the big picture before you start to worry about the minute details.
it will be fully open label for dosage so no one has to worry about 350mg of caffeine and dangerous combinations of overdosed stimulants. Flavors will be light, sweet/sour, and fruity. Possibly some iced tea and berry based flavors. If you’re familiar with innovapharms Enduralean flavoring or nuvital super spinach (same company) it’ll be close to those
