To my current knowledge, this is a task: the longest Proca Retractor AntiCirce Wenigsteiner. The previous record (18 moves) was held by Paul Raican.

The black King far away from of the edge of the chessboard seems to be a novelty in this kind of problems. Andreas Thoma was the first composer who successfully realized Proca Retractor AntiCirce in Wenigsteiner with bK not initially placed on the edge.

Here, thanks to a draw pendulum, the bK is decoyed to the edge of the board. As typical in this kind of compositions, white needs to employ several successive preparatory plans in order to reach its objective.

A truly outstanding achievement, which will hopefully become a candidate for the WJP 2016 selection!

And as I have just found out, there is longer Wenigsteiner Proca retractor in existence, by AL too:
