(sorry, this post is quite long)
Some days ago i looked into HH3. That´s the result:
I´ll start with the final combo:
The final combo might be either the one, Cut described (1: Make a SJ to reach the platform with the tribelle, take there everything, fall down, continue with the hoodlums, the matuvu, the piggybank and the gems under the hooks) or you could play the combo with a changed beginning (2: Break the piggybank, take the gems, kill the hoodboom, convert the lum, perform a SJ to reach the platform with the tribelle, take there everything, fall down, take the yellow gem, jump on the next platform, take the gem, kill the hoodblaster, continue as described above).
PYYYR|RRHLY|YYYYY|YTYYY|HLYHL,RELYY,YYMaEY,YYRRR,YY
I don´t really like this variant, since you have to perform a SJ while playing a combo, but it yields many points.
For following calculations i´ll assume that the final combo is possible and that the powerup will last long enough (i haven´t tried the combos above yet).
I´ll also assume that my calculations in part 1 and 2 are right (86110 points after part 2 with the harder version of the 3rd room combo; 85090 points after part 2 with the easier version of the 3rd room combo)
Variant 1 - points:
Points you can get in part 3 before playing the final combo: 11180
Points from the final combo: Basic: 3500; Combo: 13200
Since the last item is a yellow gem, the maximum is: 100009 + 13200 = 113209
Points you need before playing the final combo: 100009 - 3500 = 96509
Points you must have after part 2: 96509 - 11180 = 85329
Points you may lose, when you´ll play the harder version of the 3rd room combo: 86110 - 85329 = 781
Points you must find, when you´ll play the easier version of the 3rd room combo: 85329 - 85090 = 239 --> 240 points
--> That means, that 113209 points in HH should be possible. If you could convert that lum in the warehouse combo (part 1) and get more gems in the secret room with the vortex, or if you could improve the third room combo in HH2, you should be allowed to use the easier version of the 3rd room combo.
Note: This calculations are made for players, who are not using the IPG or the lums glitch, but they must be able to get the heckler for 2500 combo points.
With the lums glitch the maximum might be higher.
Variant 2 - points:
Points you can get in part 3 before playing the final combo: 10080
Points from the final combo: Basic: 3700; Combo: 15460
Since the last item is a yellow gem, the maximum is: 100009 + 15460 = 115469
Points you need before playing the final combo: 100009 - 3700 = 96309
Points you must have after part 2: 96309 - 10080 = 86229
Points you must find, when you´ll play the harder version of the 3rd room combo: 86229 - 86110 = 119 --> 120
--> That means, that 115469 points in HH should be possible, If you could convert that lum in the warehouse combo (part 1) OR get more gems in the secret room with the vortex OR improve the third room combo in HH2.
Note: See note above.
Maybe you could convert the lum from the last elite monger too. In that case the maximum should be 100 points higher.
If someone wants to go for the maximum, he might maybe use an improved 3rd room combo. The difference to the "old" version would be, that you´d kill only two hoodblaster in the beginning. YYYYY|YYYHL|HMuYRG|YRRYE|YYYYY,HMa
When the "old" version works, this combo should work until the 20th item too.
As far as i know, i could take the gems in the secret room, roll off, kill the elite monger, renew the vortex and get the yellow gems in time. Killing the hoodblaster and taking the matuvu in combo is probably possible as well, so i guess it should work completely.
Sadly it doesn´t include the red gem near the elite monger (except if you could roll off the secret room, take the gem and then killl this hoodlum), so you´d have to either take it outside of a combo or, if you could influence where black lums are flying away, convert the lum from the hoodblaster committed suicide just before taking this gem.
A question i wanted to ask longer time ago already:
Why does following not work (or does it work?): (BOM6) Weaken razoff until the next six hits will kill him. Hit him five times and defeat him with the sixth hit (score: 101499 + 6800 =108299)
As far as i know, the sixth hit won´t reduce razoffs life, but why?
About the Heckler in HH2: I´ve made a few tests and I could kill him after two "tries" (the shield has to be only two times up). I guess that means, that it´s possible for me to kill him for 2500 points or not?
Cut said:
Finished FC with 48.820 points. I guess that's not terrible.
Congratulations, that´s a good score! What will you improve next? I guess CF or HH.
By the way, Maz, how are you doing with your no-glitch-project. I guess in some places it´s quite an interesting challenge (like CF2)

.
I also guess that 100k in BOM won´t be possible any more (at least no annoying razoff glitch). Is actually the razoff glitch/trick in part 6 a glitch in your eyes?
