Hi
@Jonnybarr91 , and welcome to the ECF community!
PJ asked, but I didn't see your response; where did you buy your flavor concentrates? Was it from a local shop, or on line? It can help us give you better info if we know where you are buying.
A note about the "15-20%"recommendations:
Some (many?) of the major flavor concentrate manufacturers were around long before vaping. The majority of their customers sales come from (and are directed to) the food and beverage industries. It is for
that use you are seeing such high percentages (not vaping). I generally ignore them completely; unless they are coming from a vaping specific (and vaping only) website. And then, I still take them with a grain of salt. I also read the buyer reviews (when available) to see what they are saying worked for them.
PJ gave you a useful resource when she suggested E-Liquid-Recipes (ELR) website. Besides being able to create a personal flavor stash, to search for recipes using only your ingredients; you can use the Flavor List (found under the Resource Tab), to see how others are using any particular flavor. This includes minimum/maximum and average percentage used. This is what you Blue Raspberry Cotton Candy looks like (in part):

PLEASE keep in mind:
The "pecentages in recipes" values are based
only on the recipes entered on ELR;
and they are based on
all recipes on ELR. This includes good recipes, bad recipes, and works in progress. So this info is "broad brush" at best. But at least it can give
some idea of what others are doing. It also isn't able to tell you if it is being used as a primary flavor (the main taste), a secondary flavor (complimentary, contrasting, or supplemental tastes), or only as an adjunct (not really there to add "taste," but to influence the rest of the mix (e.g. soften harsh notes; add sweetness, juiciness, mouthfeel).
Regarding single flavor percentages; I tend to give this little influence on my mixing decisions. It is not uncommon to see only 10, or fewer, users opinions. And when they may range from 1% to 30% (or more) that really isn't helping me much.
In general terms, I tend to start at the lower end of the spectrum, and add
s l o w l y, in small increments, until I find my sweet spot.
Another useful tip for ELR:
I find, that when entering a flavor name to search, it is best to not identify the vendor. There are just too many ways people choose to do it (and each variation creates a "new" ingredient profile.
Instead, to find the most commonly used format, I enter the name (completely and accurately), and then hit search. The results will come up in alphanumeric order. Here's an example for raspberry:

Chances are the one you want is not going to be on top (not even on the first page many times). So, to bring up the most frequently used (in recipes) by clicking on the recipe bar/tab, and it will resort the ingredients, in order of frequency found in recipes. It now looks like this:

Now I can click on the flavor name, and it will open a window, with the details for that ingredient.
The intent of sorting in this manner, is to find the most common entry method, and therefore get the biggest sample group for the flavor. The bigger the sample group; the better chance of smoothing out the influence of unusually high/low usage on Percentage averages. It will also (hopefully) provide more feedback in the "Notes" section found below the averages.
Using this sorting technique is also a good idea when creating your own flavor stash too. If not, and you select one of the unpopular formats (even though it is a popular flavor), you will get significantly fewer recipe suggestions (or even none at all).
For further help using the ELR site; I would refer you to their own forums.
A final note on ELR:
ELR is a bit persona non grata on ECF. Please don't ask why; just take it as fact. The administration sets the rules, and we have the choice to follow them, or go elsewhere. It is tolerated to mention by name, or its common ELR abbreviation. Even screenshots from ELR are acceptable, as I have done above (just don't include the URL address bar; or header in your screenshot). But, writing out the URL (???.com), or attaching a link to their site is prohibited, and usually gets automatically filtered out. The result will be a string of periods (.....................). If you see that, just don't do it again.
