Should One Sell Experience Books II

Earlier I posted some opinions and figures on selling experience books.  My conclusion was: you should not.  That, assuming you play a lot: you are in a guild, finish all the subgames each time they are offered, and do 2.5 quests per day.

However an anonymous poster corrected me.  I assumed you'd go to level 200 at each level of evolution, even though you need only go to 180 (uncapped) or 185 for evo 1 and 2 respectively.  Duh!  Embarrassing mistake.  Let's correct that and recompute.  (Obviously anonymous already did this computation, but I'm showing the work here.)

So, experience.  Here's data.  To fully max out a hero at 200ee, you need level 180 then 185 then 200.  Level 180 requires 77508850 EXP; level 185 takes 100486350 EXP; level 200 takes 208918850 EXP.  200ee thus takes 386914050 EXP.  Similarly, 200ee takes 3 full sets of honor badges to 200, minus a handful of the little ones.  (When you evolve, you don't have to do the small levels.)  The total required is 814,000 + 800,000 + 780,000 = 2394000 HB.

Thus, in terms of outlays needed to max heroes, the ratio of EXP:HB is ~162.  If we earn more than 162 EXP per HB earned consistently, then books will pile up unused (and heroes will be blocked) and we should sell some books to equalize.

As I posted in the original assessment, the total experience I am earning per day (at Insane 4-10 and HBM S) is roughly 14.2m/day. 

Similarly, I am getting about 50000 HB/day from all sources. 

9.4m/50000 is ~188.  This is slightly above the breakeven point above.  So I was wrong: at least with these numbers, I will want to sell some books.  I doubt all of them, because it is close.  But I'll have to pay attention.

Also, as anonymous points out, you can increase experience by the Enlightenment talent.  I do this as much as possible.  For example right now I have Enlightenment 1 on my DD, who I am taking to 200e (I have no dupes for him).  Then I'll work on Medusa, with Enlightenment 3, again to 200e unless I get wildly lucky on some gem rolling.

20% extra experience is nice.

One more good point anonymous made.  Some people stop heroes at 180ee (uncapped), which saves 131410000 EXP; the ratio of earnings in that case is 255504050/2394000=~107.  I don't think this is necessary, but if you are super tight on honor badges, consider it.

So, why do have so many honor badges?  My guess is because I have only recently gotten to ID4-10; I was stuck sweeping expert dungeons until last September.  The different in experience is rather large.  But now that I am sweeping ID4-10, I should expect to run dry pretty soon.
