Let's have a look.
Invisible layers of solid force surround and protect the target, granting that target a +2 armor bonus to AC. Additionally, the first 5 points of lethal damage the target takes from each attack are converted into nonlethal damage. Against attacks that already deal nonlethal damage, the target gains DR 5/—. Once this spell has converted 5 points of damage to nonlethal damage per caster level (maximum 50 points), the spell is discharged.
Add half your tier to the spell’s armor bonus. Add half your tier to the amount of lethal damage from each attack that is converted to nonlethal damage and to the DR against nonlethal damage. Add half your tier to your caster level when determining how much damage the spell converts before it’s discharged.
Effects of Mythic Spells: Unless otherwise specified, a mythic spell works just like the non-mythic version of the spell. For example, zombies created by both animate dead and mythic animate dead count toward the spell’s HD limit of how many undead you can control at one time, and a chaotic creature is immune to mythic chaos hammer in the same way it’s immune to chaos hammer.
Unless a mythic spell’s description says it improves, replaces, or upgrades an effect of the non-mythic spell, or says that it creates an effect instead of the non-mythic spell’s effect, it retains all the effects of the non-mythic spell in addition to the effects of the mythic version. For example, the mythic blasphemy spell has penalties for creatures that fail their saves; because the description doesn’t indicate that these penalties replace those of non-mythic blasphemy, the penalties are in addition to the non-mythic spell’s effects.
The mythic upgrade changes by adding half your tier to:
- The armour bonus granted by the spell.
- The conversion of damage to non-lethal.
- The damage reduction against already non-lethal attacks.
- Your effective level for calculating the bubble's ability to convert damage.
It does not change:
- The cap of 50 points of conversion potential.

The conversation is in regards to just that though.
When it says "per caster level(max 50points)" in the spell description, in terms of Caster level, it is saying "Max CL10".
In the mythic version it makes no reference to a max amount/CL. It is upgrading the "max CL 10" to be caster level+1/2 mythic tier.
That is where the hang up on it is...

It doesn't say it upgrades the max anywhere. An magus 8 normally can convert up to 40 points of damage to nonlethal with this spell; if they have 2 mythic tiers and know the mythic spell they can convert up to 45 points of damage to nonlethal. Nowhere in the mythic spell does it suggest that the cap is changed, so an magus 10 with 2 mythic tiers can convert up to 50 points of damage to nonlethal with this spell.

The mythic version says to add half your tier to your caster level when determine how much damage the spell converts before it is discharged. It does not mention increasing the maximum so that would mean the increase in caster level only will only increase the amount until it reaches 50.
So at caster level 5 with 2 mythic tiers the standard version absorbs 25 points, where the mythic version absorbs 30. depending on how fast your gain tiers the mythic spell probably maxes out at level 8 assuming 4 tiers instead of at level 10.
