Just be slow with the direct T1 links...3-5 per day for a week or two. Then maybe ramp up to 10 per day for a few weeks, etc. You just drop in a T1A after a week or two, then a T2, then a week later add a T2A, etc.
Grow it with increasing link velocity, but start small. Most of your link velocity will come from underneath, so don't get in the habit of blasting the T1, because you will disappear.
Forget all this man made stuff. If you created manual T1's, then stick those in your T1 and that's the end of it. If you have another service or software creating T1's, then you obviously need to continuously update your T1 project with any new URLs.
Dropping in a T1A, T2, T2A, T3, T3A means drop in a new project. It's building links to each URL in the project directly above it. I usually start T1A, T2, T2A, T3, T3A at 10X per URL. Then once I have the whole 2 or 3 tier structure fleshed out (depending on how deep you make this), I will then turn up the dial on each project, one by one, starting at the bottom, probably one week apart, to 20X (from the previous 10X).
You never decrease link velocity. If you get where you want to be with your rankings, then stay at that link velocity to maintain your rankings.
Use tools like ahrefs or majesticseo to make sure you are not entering negative link velocity. Links get killed over time. You have to make sure on a net/net basis that your total links are flat or ascending. If you don't watch this, your rankings will tank.
Here is an example from ahrefs of a website that lost rankings because it lost link velocity (it lost more links than it gained):
Pretty interesting, right? Those little red and green marks show that more links are getting lost (red) than being built (green).
So remember, just because you build links doesn't mean your boat won't sink. You have to maintain neutral to positive link velocity.
You're talking about indexing. I use the Lindexed API in SER which helps. Ultimately the best way to index links are to backlink them, and that's what you do with tiering.

Don't confuse the effect of T1 links versus those that do not hit your moneysite directly. With the lower links, we are talking about link juice. With the T1 we are talking about actual links. Those are not the same thing, so you do not have any cause for concern.
And good luck on getting 50 T1 links and 250 T2 links indexed at the same time, lol. You would be lucky to get 20 links indexed the first week. So if you figure out the secret to fast indexing, open up a website and charge people $1000 for that information. We all want that.
I just set the project to pause at my limit and forget it. I obviously keep my eye on verified to see if I am getting what I want for verified, and if I am not, I make a small increase to the submitted.
On lower tiers, I set it at 10X Per URL. So a T1A with this setting will submit 10 links each day for every T1 verified link.
@rancher92 - Just follow this https://forum.gsa-online.de/discussion/2930/ser-tiers/p1
@mishav, for large sites, I would clump as many pages together in one project, and shoot a link or 2 per day at each.
