Hey Iamready,
Great video man, I mean it. Your insight into your reason for LL are ones that I can appreciate deeply like DITFM.
In regards to your goals, I think doing 5 CM on tibia is a good goal. Many of us here in the forum consider 5 cm on the tibia to be a safe limit; it's one where recovery is solid for the most part. Don't be discouraged by it, get to the 5 CM and don't become so picky over .something of a CM. The payout will come from the femurs.
This sort of brings me a point I've wanted to ask for awhile now but I was scared to ask considering how personal and subjective it can become. But how do you feel in regards to proportions? Considering your goal now seems to be 5+8=13CM, I myself wouldn't do so much because of proportion sakes (even though in regards to each segment, those numbers are good for recovery). I don't mean to sound discouraging but to me personally it does strike me as too much; for some perspective I've basically settled for 8 CM total (4+4) for proportional sake. What's your perspective on it?
Cheers, wish you a good holiday seasons and the best with LL.
