About ようが～まいが
When both the positive and negative volitional auxiliary verbs are combined with a verb in Japanese, it has the nuance of 'whether or not (A)', the result will be (B)'. This is quite emphatic, and has a literal meaning similar to 'say it does (A) or say it doesn't (A), it will still be (B)'.
As a reminder, the positive auxiliary verbs of volition are either う or よう, depending on what they are being connected to, while the negative auxiliary verb of volition is まい. Either the case marking particle が or と will appear after both the positive and the negative, with が being slightly more common.
While this structure is primarily seen after verbs, it is important to remember that other auxiliary verbs such as だ can be conjugated in the same way, as can い-Adjectives with the less common かろう structure. This means that nouns, な-Adjectives and い-Adjectives can also appear using a similar grammar pattern. However, because the negative volitional まい cannot pair with these structures, an antonym will usually appear with them instead, with both words using the う or よう positive volitional.
Based primarily on the use of volitionals, this grammar pattern will often indicate the speaker's strong will or opinion that will not change regardless of (A).

This grammar point is A Lot.
I’ve never encountered Adjective［
い］+ かろう before now.Is there a chance this can be worked on a bit? I’m finding it really hard to get my head around this because this part:

Tough call I think…
Up until this point, かろう has not been introduced for adjectives at all, so that should be a fun-fact more than anything. I would say the easiest way that we can condense this is to focus the scope of the article, while making it less about the various forms it can appear in.
We do have かろう, but it is not something that is strictly covered in the JLPT, for now at least.
Probably the best way to handle it would be introducing まいが as the exception to the doubling rule, with verbs, and then simply introducing the rest as structures that double, as all of those (apart from かろう) should be very familiar for everyone by that point.
