Your calculations only work in a vacuum/target dummy scenario. You wasted a lot of time I’m guessing doing all that work for nothing. Practical application is far different.
Your only metric of qualification for his damage out put is the numbers themselves. You completely omit several important factors such as self healing, armor, ease of escape, CC, and movement speed. In a vacuum, Tychus will do the most damage but in practical application, his lack of reliable self healing, limited escape potential, squishiness, and self peel capabilities reduce his overall damage.
Since you conveniently ignore important factors in order to concoct a flimsy impractical one-sided narrative, I’ll do everyone a solid and post mine here:
1.) Soundwave knockback. Can be used to peel dive heroes (Illidan, Malthael, Tracer) off of you, extending your presence in the team fight further. Interrupts ETC powerslide and Diablo charge, negating some counters you think Lucio would be subjected to.
2.) Constant self healing. I take Smooth moves on 1 for even more healing and mana regen. His enormous amount of self healing allows him to stay deep and stay there long.
3.) Armor from slip. Basically a permanent 20 armor that never goes away that also comes with a convenient 40% movement speed escape tool baked in.
4.) Sound barrier. Essentially, four free seconds of prolonging your dive, allowing you to get even more damage in. Also acts as a safety net, allowing you to solo dive and have a get out jail free card in the pocket. Can be used every 30 seconds to non-stop dives in the endgame.
5.) Push off. Lucio’s great escape tool. He wouldn’t be able to dive nearly as deep or hard without this baby to fall back on when things get hairy. Also doubles as a nice spike of burst damage to combo with Q. Up to 10 second cooldown with the right talent.
6.) Movement speed. At a 150% speed with accelerando or 130% with smooth moves (same as mounted), you can literally do circles around certain heroes who don’t have gap closers or point click CC to catch up with you. This makes him more slippery and again, allows his dives to be riskier since your ability to escape is high.
Tychus has tools in his kit to be fair; dash (up to 2), comes with movement speed. A long CD self heal that is reliant on damage dealt at 13. Potentially long knockback with extra knockback grenade talent. Odin gives unstoppable and 25 armor.
However, these tools pale in comparison to Lucio’s arsenal. Essentially, you are right, Tychus has more theoretical damage, but Lucio has more practical damage as a result of his tankiness, difficulty to kill factor, and non-stop sustain damage.
Lucio never has to back off, never has to sit back and wait for CDs, and never has to worry about being jumped on by DPS. To be fair, there are exceptions. He is weak to point click CC like Uther and Murky. But in situations where those counters aren’t present, I’d take my lucio over your tychus anyday, even against a beefy tank enemy team.
