That does seem odd. Digitaltruth has the following:

Film Developer Dilution ASA/ISO 35mm 120 Sheet Temp Notes
Efke 100 Rodinal 1+50 50 9 9 20C
Efke 100 Rodinal 1+25 80 5 20C
Efke 100 Rodinal 1+25 100 6 6 6 20C
Efke 100 Rodinal 1+50 100 10 10 10 20C
Efke 100 Rodinal 1+100 100 16 16 16 20C
Efke 100 Rodinal 1+25 160 8 20C
Efke 100 Rodinal 1+50 200 14 14 14 20C
Efke 100 Rodinal 1+50 400 24 24 24 20C

Marko,

You could also refer to the Efke website. That suggests 1+25 for 6 minutes at 20°C, which happens to be the same as one of the MDC suggestions above and the JandC times.

Best,
Helen

Try Rodinal 1+100 for around 19 minutes. Works really well for me (in 120). 5 inversions at the start of each minute for first three minutes, then one inversion every three minutes thereafter.
