How many paragraphs for high level 3 in a15 Marker [AQA ALevel Economics Paper 1]

For AQA ALevel Economics in paper 1, I was wondering whether it'd be a better idea for me to do 2 paragraphs for the 15 marker in paper 1 or to do an introduction and 2 paragraphs, or to do 3 paragraphs in less depth, because when I've been doing questions, I've been spending too long on the 15 marker and don't have enough time for the 25 marker. Is two paragraphs still enough to get into the top part of level 3?

I dont do economics but business so the structure may be different but surely have relation, we are taught to do this:

-------------------------------

X MARKS - COMMENTS - AO MARK EQUIVALENT PER QUESTION

3 markers - small points, usually calculations (show all working) - AO1 1 - AO2 2
4 markers - small points, usually calculations (show all working), show knowledge, analysis and application - AO1 2 - AO2 2
9 markers - 2x PECAN paragraphs, explain how, analysis actions,, explain using calculations, analysis with reference to theory, no evaluation - AO1 3- AO2 3 - AO3 3
12 markers - 2x PECAN paragraphs, explain how, analysis actions,, explain using calculations, analysis with reference to theory, no evaluation - AO1 3 - AO2 3 - AO3 6
16 markers - 2xPECANPIE paragraphs, to what extent = must decide, show balance, AJIM conclusion - AO1 2 - AO2 3 - AO3 4 - AO4 7
20 markers - 2xPECANPIE paragraphs (2 points in each), show balance, more contextual analysis and longer conclusion than 16 market, AJIM conclusion - AO1 4 - AO2 3 - AO3 5 - AO4 8
24/25 markers - same as 20 marker just much longer AJIM conclusion, add multiple "it depends" points, and make it at least 2 paragraphs - AO1 5 - AO2 4 - AO3 6 - AO4 10

PECANPIE:
- PE: point explained - this is this, this is this because...
- CAN: contextual analysis - logical chain of analysis - this causes... - this means.... - the result of this is.... which does..... and this may....
- PIE: point included evaluation - explore the limitations and weaknesses of the point being argued - give the point perspective - this could be because.... however this could change this..... if this happens, then the reflection could be made that....
*note that 9 markers only want PECAN and not the PIE*
**also note why they chose to make the abbreviation PE CAN PIE and not take just the first letters of each point **

AJIM conclusions:
A: answer the question - first line must answer - I believe. this is not the case.... this point is valid....
J: justify - back up the answer with specifics, hard hitting points - this is because..... the reason being...
I: it depends - what does the justification depend on or does depend on, add perspective - however..... this depends on....
M: most important point - consider all aims and end off the conclusion with the most relevant point - ultimately I think that..... overall I believe...
