Thank you gd barnes for double checking!
So it is time for an update...
Since the confinements in belgium last / this year I cannot dedicate full time to this project
I am staying with my elderly parents to take care for them
I will see what I will decide when my last sieving range is done
I hope that I soon can return home and finish this range
Fyi I’am using srsieve 1.54 on my intel mac 2015 model
Kind regards
Valerie
