When drop?

So I no lifed the game this week to try a bunch of specs in delves to pick a main. Hereās what happened so far
VDH - map in second bountiful
BDK - map in third bountiful
Retro Druid - map in 7
Mistweaver - map in 9
Pres Evoker - map in 3
Prot Pally - map in 3
Holy priest - no map, 8 done so far - hoping to get it tomorrow in the first 3 so I can use it by the 4th

If you donāt get one, remember that the Wave Scrambler summons the Underpin and you can get one from him. Find a Delve with an open area in the beginning and summon him. Wave Scramblers can drop from curiosities and caches.

Yeah I have done multiple chars and itās very random. I think I have done delves on like 6 characters. 3 of them have gotten maps. The ones that got them did so very quickly. On my dk, I literally had the underpin spawn on my first pull.

I only played 4 characters last week and my druid got one in the first 2 delves, my monk got one after 6 delves, my rogue still hasnāt gotten one, and my pally got one on itās 2nd delve.
I didnāt have time to no life the game, just enough to hop in a few delves in the evening and get the delve vault slots opened on each character. Doesnāt seem to be much different of a drop rate for me compared to last season. But itās only been a week, so weāll see 
5 characters, enough delves to fill vault, no map, no scrambler on each of them. burned all coffer keys also

Yeah this toon got his map first 8 delce while my disc priest did about 8 or so until FINALLY getting one.
Was totally worth it, got a heroic helm so now got 3/4 set
It took a hot minute but I got it to drop on my Mage alt after about four Delves. Came from Underpin after he showed up at a very annoying time and managed to get me killed while Iām was dealing with Kobyss.
Not exactly happy for the pity reward (I managed to fend him off every other invasion attempt) but what can you do. It just seems hyper random.
I am more upset that the Hero item in question was the āGoo-blin Grenadeā. That item should go to Guuah, it would be the most fitting thing.

I got one scrambler to drop, and one map to drop, but thatās over like 8 different characters, too. Really disappointed, I was under the impression after 4 you were simply supposed to get one.

Iāve had 6 drop this week and 1 scrambler that Iāll save for when I need it. Most dropped in the first couple delves, a few were on the 6th or 7th.
I did not know this. Good information to have.
I gotta say that now that delvers bounty is a ONCE per weekly reset drop, has caused (in me) not to grind delves anymore like I did last season.

I donāt get why the mapās still random if we can only get one per week anyway. They might as well just get rid of maps completely and have the map reward box come from a weekly quest or something.

Not a fan of how random it is, some on first some none after 10 delves there should be bad luck protection after like 5 if you ask me

Or first delve of the week like how the first Timewalking drops your quest item
For what itās worth, there is bad luck protection for maps now. But itās still weird to me that itās set up the way it is because of the whole one-per-week thing. RNG loot typically doesnāt have a cap. 
Feels like weāre caught in a middle step between the S1 design and what will probably be a different iteration in S3.

If itās helpful I did 4 bountifuls each on 20 characters this week (18 did 7s, two did 8s).
8 got a delverās bounty from an end chest within 4 delves.
5 got a delverās bounty from an Underpin spawn.
7 havenāt seen a delverās bounty yet.
7/(20-5)=46.6% [roughly 50/50?] to get a delverās bounty from a chest within 4 delves at 7-8 difficulty.
Edit: If you can still get a delverās bounty from an end chest after getting one from an Underpin spawn as others are reporting then this actually drops to (7+5)/20=60% of no map from an end chest within 4 delves instead, which would be pretty demoralizing imo.
Disclaimers: Small sample sizes beware. Tried to do a running cumulative tally but itās wonky from characters being knocked out of the running whenever they got a drop from the Underpin so the final number is the most useful in any case.
But if curious:
2 out of 19 eligible got a bounty from the end chest their first bountiful delve (10.5%). [1 Underpin drop mid-run]
None of my characters got a delverās bounty their second bountiful delve from any source.
4 out of 15 eligible got a bounty from the end chest their third bountiful delve (26.6%). [2 Underpin drops mid-run]
2 out of 9 eligible got a bounty from the end chest their fourth bountiful delve (22.2%). [2 Underpin drops mid-run]
10.5%+26.6%+22.2%+46.6% is >100% because knocking out Underpin drops kept altering the sample size and if thereās a way to account for that I definitely donāt remember enough of it from doing stats class back in Wrath.
Did see more than 5 Underpin spawns as well but some of them killed me in the middle of trash.
Went in assuming your first run of the week would be a guaranteed map. Definitely wish it was.
Got it on my monk ,extra chest dropped nice hero grade trinket.
Iām not sure if cap for gilded crest was 21 per week from delves but my monk somehow got 31, i think that extra chest may have contained gilded crests as well.
One of my alts hasnāt seen one in 7 runs. All were tier 8 runs.
I am not spending 3K (which is what they are going for on Dalaran) to spawn him (and not even close to 2K in currency), and hope I stay alive long enough to get the map reward.
Completed x8 T8 Delves on my BM Hunter for the week and completed a few T8-T9 yesterday. Today, I was milling around in Fungal Folly, in a non-Bountiful T8, Underpin spawned, defeated him until he reached 50% HP then disappears, left me a Bountiful Map, took that to a Tier 8 Bountiful Sidestreet Sluice, at the end, my BM Hunter looted a ilvl 649 Haste/Mastery Hero quality Gun. Pretty good since I needed a weapon upgrade! 
I know Blizzard increased the drop chance of Bountiful Maps, however, the chances of Underpin spawning is lacking. Sure, Itās RNG, I get it, however, with players completing 10+ Delves without Underpin spawning is bothersome. Why not also increase Underpinās spawn rate as well? Iāve experienced Zekvir popping up more often in Season 1 than Underpin has in Season 2 thus far.
There is also an consumable called Wave Scrambler 2000 to forcefully spawn Underpin as well, I checked my servers AH, a single one is going for 37,000. Crazy. But, yea, thereās that option as well if youāre down on your luck having The Underpin spawn during your Delves.
