Cool. I almost tweak my solution to 1942, maybe 5-10 minutes tweaking one node, which is boring. But it doesn't matter, I found absolutely different solution, yahoo!!!
yea it's possible with slightly less speed but to get the 1948 you get that extra speed .I have solutions that don't need it but they have a slower approach .We will never know unless you do it....

Please for everyone don't believe ANY scores I post ....
