Excellent guide, well done! Just one suggestion, during long jump, you definitely do want to swing your arms in a windmill fashion. It will make you go further. Also, you don't do it when you're running, you do it when you are in mid-air. Thanks for putting up a guide, I can see a lot of effort has gone into it, so kudos to you.
Done with achievements.
I apologise for any incomplete achievement guides.
