Russian Stitch Variant 2+1+1+1rus F2

Hansen's Notation??  

Variant of Russian Stitch 2+1+1+1rus F2 front side

Variant of Russian Stitch 2+1+1+1rus F2 reverse side

My experiment of a variant of Russian Stitch 2+1+1: 
First do the RS 2+1+1 as usual, then pick up a 4th loop behind the thumb "in the Russian way" (ie from back to front, needletip pointing to 9 o'clock) a loop that has already once been picked up in the Russian way. In this manner the last loop gets twisted twice.
