> Unless you want to go into one of the full assumed fit styles, the highest frequency will probably be along the lines of:-

If you are going for frequency you should certainly not overlook assumed fit styles.
2♦ = 4+4+ majors (weak 2-suiter or strong 3-suiter)
2♥/♠ = natural weak 5 or 6 card suit
must rate a total frequency higher than most other combinations. I'll let you do the sums ...

The OP already has issues with 5-4 preemptive styles so I strongly suspect assumed fit methods are going to be a step too far. And I do not need to do the sums because Chris Ryall already did them. The assume fit style where 2♦ is natural and 2♥ shows the majors will be more common than the one you posted. The classic example of this is Frelling but Ryall has a whole page devoted to this style so it seems easier just to direct the OP to the site and he can check them all out in one go.

Can't help but note that the Frelling Two's were my own contribution to the milieu.
I crafted the response structure as means to pass the time when I was hiking from Pamplona to Finestere 10+ years back...
Good times...

Thanks Peter, I found a Mathematical Probabilities Table on the BridgeGuys website. This table does not include a HCP range for any specific distribution.

Minor mistake on their tables.

5-4-3-2 should be 5-4-3-1
