As MN had noted, watch out for what routes are conditioned out by the points. However, one word of warning here, be consistent with your decision as to whether shunt routes have an overlap. I've assumed you are looking at UK mainline from your bio entry.
Routes in the same direction to another destination are not going to be opposing routes - applies to all of the routes you have done (at least you were consistent). You have correcly picked up routes in the same direction to the same destination (ie the Call On against the Main).
112A(M) I would have expected to see AD for time in there so that 112 A(M) can be overset when the move up to the LOS has been used and its train is now going away, but still on AD.
112B(M) For the alternative overlaps, I would not expect to see the hinge points in the availability column. 301 are not hinge points as there is no overlap into the siding. 305 would probably be included to ensure that anything off the branch is trapped. 107A(M) and 107A(W) are not conflicting because of the point conditions for their overlaps. 202A(S) and 107A© should have a time off condition (as comment for 112A(M) above.) Also bear in mind that the comment below about where the train may stop for the time off. Take care with your brackets on the point conditions. (AC, AB or 302) means only AB is conditioned by 302. It would need to be [(AC, AB) or 302] for them both to be conditioned.
112B© Same comment about 107A(M) and A(W) applies. Where you have two tracks in the section where you are looking to time off the route, be careful that you include the combinations. They both need to be clear and for timing, you need to enable this to happen for either of them, hence the bracket befomes [...BG, BH ---- or ---- (BG or BH) for time]. For a call on, you normally prove the relevant TC occupied in the route requirements.
I'll have a look at the points later.
