What if we flipped the months and jumps part of your new idea... Rather than using months, several months, years, etc. Let's take the MR100 and flipp-a-roo. What's your CR(currency rating) for One Month? Your 1-Month CR? Your reply, is: 35 jumps. As in over the past month you've made 35 jumps. You could also ask the 3-M CR for how many jumps made in the last 3 months. This would get down to the nitty gritty details. If a team is doing hair raising RW and needs the hard core up to date very current folks.. they can ask your 1-Month... or a dropzone could ask for your 3month or 6month to decide if it's Refresher course time for you. If you apply to do a 30-way and your 1-MCR (one month currency rating) is: 2 jumps... you'll probably be asked to get more in before jumping with the group, regardless of your total jumps. I understand the earlier point of the skydiving knowledge coming back to you. I mean heck ya I haven't been on my bike all winter, and gee didn't even ride it that much last season. But do you think I'd be able to go ride it right now (assuming the tires have air)? You bet! But should I tackle a Downhill mountain biking tournament? Maybe you could, but I'd want to get a little more peddle time in before throughing myself down a mountain. It's a safety thing. By yourself- in the end it comes down to you. You pulling the rip, and you knowing what the hell you're doing. If you're rusty and kill yourself, it's your bad. However, if you're in RW and around other people it becomes more than that right? It's now their call on whether they want to jump with a 6-MCR of 4 jumps (6months, four jumps). There are flaws of course... After the winter blows over, those that didn't fly south for the sun will have low CR. But everyone knows that, so we take it in consideration. And maybe its this that makes the most sense. We could make a complex formula... CR over total jumps = main CR% or other modifications, but in the end it's down to us taking responsibility for looking over each other's logb.s and being brutally honest with ourselves (and our buds) with safety in mind. As a crazy vid dude said to me on my first AFF... him: "What's the most important thing to do?" me: " Pull!" him: "What's the second most important thing?" me: "umm.. ummm...????" him: "HAVE FUN!" me: "they didn't teach us that in class..." So safety first, and keep it real. We don't jump to have to go through safety procedures left and right. We jump to have FUN, and the safety procedures are what keep us alive to jump again.
