I just want to make sure I'm doing this correctly so please, anyone who knows, correct or clarify.

If the haplogroup in an FTDNA project haplotype line is RED is predicted and no deep clade R test has been run  and if it is GREEN then deep clade has been done, right?

It is here the challenge.  On GREEN haplogroups that are listed as R1b1b2 that just means they are M269+, right?   But we shouldn't assume they are P312- because they may not have taken the deep clade R test recently, in which case the P312 test may not have even been run.   Am I right?   Is there anyway to tell if an R1b1b2 that is GREEN is a true R-M269* (negative for all downstream markers)?

Same general issue on R1b1b2a1b.   That is the label for R-P312, right?  If someone is R1b1b2a1b how do I know if they are true R-P312* (negative for everything downstream) or if they just happened to done the deep clade before L21 testing was included?

These labels are right, correct? I'm getting them off my FTDNA haplotree page.
R1b1b2a1b - R-P312
R1b1b2a1b5 - L21
R1b1b2a1b5b - R-M222
R1b1b2a1b4 - R-U152* and its variants have letters after them

If somebody has had the full 67 test there are markers that can suggest R1b1b2a1a, and if you run comparisons on a full set 67 set of markers and find a bunch of people with close matches who all share the same haplogroup then I don't think it would be unfair to guess that person is also a member of the group. However I suppose the truefull answer is you can't really tell unless somebody gets tested.

May be it would be a good idea for FTDNA to introduce a system for identifying the presence of untested SNPs downstream of people's results?

Yes, a green entry has been SNP tested, but not all SNP tests are equal. Red entries are predictions.

There are people who had the Deep Clade-R before January of 2009 who have the green "Rb1b2a1b" but who are NOT R-P312*. They were never tested for L21. There are plenty of them. To add confusion, there are people who have tested L21+ or U152+, etc., with Ethnoancestry or some other company but who have only a green (or, in some cases, red) "R1b1b2" or "R1b1b2a1b" in their FTDNA projects.

The green "R1b1b2" represents someone who had the Deep Clade-R before P312 and company were included. Some of them had the test before even U152 and U106 were included!
