What you are asking about is 'Dollar Cost Averaging', and it is definitely a bonafide strategy. Basically, you set a mix and if the market goes down, you are buying low. When it goes back up, you get an extra kicker from those shares that you bought for a bargain. Search threads on Dollar Cost Averaging or DCA for more discussion.
I followed DCA strategy with a 33/34/33, C/S/I mix for my first 20 years in TSP. And it worked out pretty well. (Although I had to stomach a drop from $300K to $160K at one time. Boy, I got new shares for half price!) It did recover nicely, but took a few years.
I don't know why a 30 year old would want to have ANY $$ in G or F. And if you are in any L, you have some in both G and F. Definitely better than all G and/or F, but not helpful in my opinion. (I gave this same advice to my 30 year old daughter.)
The actual % mix is up to you, and you may want to evaluate it once a year or so to see if you might want to adjust it. If you are all in equities, they tend to track together. But, IN GENERAL, S tends to have higher long term returns, but is also more volatile.
GOOD LUCK in your investing. Good on you for evaluating different investing strategies!! :arms:
